Title Thermal radiation of a thin rectilinear antenna
Periodical Zhur. tekh. fiz., 25, February 1955, 323-332
Abstract On the basis of the general theory of electrical fluctuations
(S. M. Rytov, Teoriya elektricheskikh fluktuatsiy i teplovogo,
izlucheniya [Thermal radiation etc.], Moscow, 1953)'and the
theory of thin antenna (M. A. Leontovich and M. L. Levin, ZhTF,
14, 481, 1944 and Izv. AN SSSR, Ser. fiz., 8, 157, 1944) the,
authors consider the thermal radiation of a thin cylindrical
straight conductor both.at nonresonant and at resonant frequen-
cies. They find the spectral intensities for density of ener
gy
flow and for total radiated power, and obtain an expression.for
the reduced.characteristic (diagram of directivity) of thermal
radiation; they also calculate the distribution of the fluctua-
tional.current along the:antenn;3 and its radiation resistance.
In conclusion they generalize all these results to.the case of a
conductor of variable cross section. Three references: e.g. M-L.

Abstract The author applies the theory developed in part !.[see the pre-
ceding abstract]-to a non-autonomous system with one degree of
freedom. As an example he considers a tube oscillator entrapped
[zakhvachennyy] by a harmonic force. By the same.method he in-
vestigates a system with.two degrees of freedom, namely a tube,
oscillator connected to a circuit with high figure of merit-
fvysoko-dobrotnyy konturl, and_clarifies the influence of this
method of frequency stabi.lization upon fluctuations in amplitude
and phase. He shows how -the thermal fluctuations are taken into'
account in thegiventheory. Five references: e.g.~S- M. Rytovj

Abstract A medium consisting of successive sufficiently thin lamina of
two isotropic substances exhibits towards electromagnetic waves
a behavior of a uniform, but anisotropic (single axis crystal)
matter. Effective permeability.tensors of such a crystal are
obtained~and limits of I-mina thickness are derived as related
to thematerial and to frequency parameters. Losses in the.
microlaminar structure and boundary conditions on its surface
are analyzed. Academician M. A. Leontovich is-thanked for, dis-

ABSTRACT: The no -linear theory of oscillations which was originated.-,
by Poincare' has since been developed intensively 'in the~Soviet~.
Union by a number of outstanding scientists, such asL.I.
Mandel'shtam and A.A. And-ronov. The 'theory is based on the
four princip-al methods: quantitative theory of the
Poincare differential equations which gives geometrical rep_
resentation of the motion of dynamic systems, in particular.)
their limit cycles; 2) the small parameter method which was.~,
originated by Euler and Lagrange, developed by Poincar4 and
employed in practice by van der Pol; 3) the method of the
investigation of stable states and periodic oscillations,and..
4) the method of broken-line approximation of.non-linear
characteristics. The second method was used in the Soviet
Union to investigate the problem of forced synchronisation

oscillations. The conditions of self-excitation in the systems
with parametric variables were studied by G.S. Gorelik and
S.B. Strelkov. The study of small non-linearities was originated
by Mandellshtam and later generalised to include systems with",,,
large non-linearities. The problem of relaxation oscillations,:-
was first studied by Mandellshtam and Papaleksi and, since then,
a large number.of works dealing with various aspects of the
problem have been published. The qualitative, theory of,non-
linear, differential equations was given by Andronov and
Pontryagin; the school founded by A.A. AndronoV in Gorki:has,
since investigated this field very extensively. Andronov
proposed also,a. new scientific theory, the so-called "general
dynamics of machines" which classifies the.Machines and analyse s
their functioning in very general terms. This theory is of,
particular importance in'the field of automatic.control, where
the non-linear problems are Darticula:i?lZ~ relevant and where
they become very complicated. ~ndronov and is schoolhav.e..
also investigated the nyquist criterion and have introduced a

blem. The finite width of the maxima of both doubletts.is connected
with the dispersion of the parameters..of the,medium. At the abs,en-
ce of losses.these maxima are transformed to discrete lines. The.
dispersion of the parameters leads to the existence of a widespread
continuous background, the distrib-dtion of which depends on the:..,
dispersion laws.
For the integral intensity of the isotropical part of the scattered-
light an expression is given. Finally the case of a liquid with,a
low viscosity is considered. There are no reference and I table..,~,

The initial equations: The author here confines himself to an isotropic

scalarcoefficients of heat conductivity and of thermal expansion. All
these parameters of the medium are functions of the.frequency 6) and
are generally complex. The deviations from the.thermodynaiaical.state
of equilibrium of this medium can, in.the case of the known restrictions,
be described byA further parameter. In the case of lacking dispersion
all equations given here are true for the spectrally not decomposed
quantities, and thermodynamics then enters into force. The..next chapter.

PERIODICAL: Uspekhi Fiz. Nauk, 1957, Vol._62, Nr 4, PP. 485-496 (ussR)
ABSTRACT: On June 27th Gabriel Semenovich Gorelik,:one of the most.
prominent Soviet physicists, died by a tragic accident. He
Vlas well known on account of his investigations on.the.theory
Of oscillations, on radio physics, optics and acoustics aswell
as on account of his excellent pedagogical activity of many
years. G. S. Gorelik was born.in 1906 at Paris, where his
father studied at that time. In 1923 he.began his studies at
~the mathematical-physical faculty of Moscow university and,
influenced by L. I. Mandellshtam, he turned to1heoretical
physics, also as an aspirant he worked under Mandel'shtam.
Then beginning to works as an aspirant (1930), he began
teaching. From 1934 to 1938 hedelivered lectures on the.
theory of oscillations. During this time fie finished seven
further scientific investigations on the theory of oscillations.
From 1935 to 1937 he worked at the physical-technical research
institute at Gorlkiy. In,1938 he took over the chair for
general:physics at~Gorlkiy, where he lived till 1953-During
Card 1/2 his stay at Gortkiy he wrote more than 20 scientific treatises

in Memory of G. S. Gorelik, 53-4-6/10
on various problems.of the theory of oscillations,
magnetism, theory of automatic control, radiophysics and
optics. When delivering his excellent lectures, he always
endeavored to combine the."classical" and-the "modern".
His pedagogical talent expressed itself in his capability,
to train scientific workers.and to form congenial collectives.
During tilt war he carried out important commissions for,
collubructiort offices working at Gorl.kiy. In the years~after
the war Gorelik took.part in the development of the theory
of the nonlinear oscillations..Gorelik developed an individual,
direction which may be described as an investigation of the
properties of matter and radiation by means of oscillation
methods and mainly radiophysical methods.
In June 1953 he was offered the professorial chair at the
Moscow physical-technical institute. Further details of his
activities are discussed.
There are 1 figure and 64 references, 60 of which are Slavic.

Title Thermal radiation of a thin rectilinear antenna
Periodical Zhur. tekh. fiz., 25, February 1955, 323-332
Abstract On the basis of the general theory of electrical fluctuations
(S. M. Rytov, Teoriya elektricheskikh fluktuatsiy i teplovogo,
izlucheniya [Thermal radiation etc.], Moscow, 1953)'and the
theory of thin antenna (M. A. Leontovich and M. L. Levin, ZhTF,
14, 481, 1944 and Izv. AN SSSR, Ser. fiz., 8, 157, 1944) the,
authors consider the thermal radiation of a thin cylindrical
straight conductor both.at nonresonant and at resonant frequen-
cies. They find the spectral intensities for density of ener
gy
flow and for total radiated power, and obtain an expression.for
the reduced.characteristic (diagram of directivity) of thermal
radiation; they also calculate the distribution of the fluctua-
tional.current along the:antenn;3 and its radiation resistance.
In conclusion they generalize all these results to.the case of a
conductor of variable cross section. Three references: e.g. M-L.

ABSTRACT: The no -linear theory of oscillations which was originated.-,
by Poincare' has since been developed intensively 'in the~Soviet~.
Union by a number of outstanding scientists, such asL.I.
Mandel'shtam and A.A. And-ronov. The 'theory is based on the
four princip-al methods: quantitative theory of the
Poincare differential equations which gives geometrical rep_
resentation of the motion of dynamic systems, in particular.)
their limit cycles; 2) the small parameter method which was.~,
originated by Euler and Lagrange, developed by Poincar4 and
employed in practice by van der Pol; 3) the method of the
investigation of stable states and periodic oscillations,and..
4) the method of broken-line approximation of.non-linear
characteristics. The second method was used in the Soviet
Union to investigate the problem of forced synchronisation
in simple oscillators. L.I. Mandel'shtam and N.D. Papaleksi
studied the "Periodic Solutions of the Second Kind" and
concluded that. in a regenerative system, it is possible to

They also devel
oped the theory of the parametric generation,6f"
oscillations. The conditions of self-excitation in the systems
with parametric variables were studied by G.S. Gorelik and
S.B. Strelkov. The study of small non-linearities was originated
by Mandellshtam and later generalised to include systems with",,,
large non-linearities. The problem of relaxation oscillations,:-
was first studied by Mandellshtam and Papaleksi and, since then,
a large number.of works dealing with various aspects of the
problem have been published. The qualitative, theory of,non-
linear, differential equations was given by Andronov and
Pontryagin; the school founded by A.A. AndronoV in Gorki:has,
since investigated this field very extensively. Andronov
proposed also,a. new scientific theory, the so-called "general
dynamics of machines" which classifies the.Machines and analyse s
their functioning in very general terms. This theory is of,
particular importance in'the field of automatic.control, where
the non-linear problems are Darticula:i?lZ~ relevant and where
they become very complicated. ~ndronov and is schoolhav.e..
also investigated the nyquist criterion and have introduced a

with the dispersion of the parameters..of the,medium. At the abs,en-

dispersion of the parameters leads to the existence of a widespread

ABSTRACT: On June 27th Gabriel Semenovich Gorelik,:one of the most.
prominent Soviet physicists, died by a tragic accident. He
Vlas well known on account of his investigations on.the.theory
Of oscillations, on radio physics, optics and acoustics aswell
as on account of his excellent pedagogical activity of many
years. G. S. Gorelik was born.in 1906 at Paris, where his
father studied at that time. In 1923 he.began his studies at
~the mathematical-physical faculty of Moscow university and,
influenced by L. I. Mandellshtam, he turned to1heoretical
physics, also as an aspirant he worked under Mandel'shtam.
Then beginning to works as an aspirant (1930), he began
teaching. From 1934 to 1938 hedelivered lectures on the.
theory of oscillations. During this time fie finished seven
further scientific investigations on the theory of oscillations.
From 1935 to 1937 he worked at the physical-technical research
institute at Gorlkiy. In,1938 he took over the chair for
general:physics at~Gorlkiy, where he lived till 1953-During
Card 1/2 his stay at Gortkiy he wrote more than 20 scientific treatises

in Memory of G. S. Gorelik, 53-4-6/10
on various problems.of the theory of oscillations,
magnetism, theory of automatic control, radiophysics and
optics. When delivering his excellent lectures, he always
endeavored to combine the."classical" and-the "modern".
His pedagogical talent expressed itself in his capability,
to train scientific workers.and to form congenial collectives.
During tilt war he carried out important commissions for,
collubructiort offices working at Gorl.kiy. In the years~after
the war Gorelik took.part in the development of the theory
of the nonlinear oscillations..Gorelik developed an individual,
direction which may be described as an investigation of the
properties of matter and radiation by means of oscillation
methods and mainly radiophysical methods.
In June 1953 he was offered the professorial chair at the
Moscow physical-technical institute. Further details of his
activities are discussed.
There are 1 figure and 64 references, 60 of which are Slavic.
All 6t+* references are scientific works by Gorelik.

ABSTRACT: In Ref 1 (Ya.I. Khurgin), an expression*has already been,
found for the spectral density of the random pulse train.,.
of Eq (1)j in which the amplitude, duration and.occurrence
of the pulses are all independently random. The process
is stationary and the mean value dispersion and distri-
bution functions of pulse spacing and length are all known.

respective "half-waves'.' are randomly independent. The
process is described by Eqs (2) (3), whence it will be seen,

problem, there is a lack- of scientific,papers,.and
the number of reports dealing with this subject,
was inadequate, even at this Conference. ~ The Con-,

which wa'a delivered at the plenary session. I.L..
Bernshteyn (NIRFI, Gorlkiy) reviewed the develo
p
ment of statistical radio physics in his report,
titled."Fluctuation Phenomena in Self-Oscillator
Networks". Already in the mid-thirties,, by sug-
~gestion and under supervision of A.A. Andronov,
the author analyzed and calculated processes in an
ordinary vacuum tube-oscillato.ro-.c.onsidering the
