TITLE: i4~)~sical Meaning of the Anomalous Law of Changing Attenuation With

ABSTRACT: It is well known that, at variance with the increase of resistive losses
with frequency common for all wave modes, resistive losses decrease with
increase in frequency for mode Hom waves in axially symmetrical round-wave-
guides. The physical meaning of this effect is associated with the fact that at
c0 -:P- co the losses of the current component oriented along the waveguide axis
are proportional to 6) 1 /2' while the losses associated with the transverse
component, LO-312. As longitudinal current components are absent in mode
Hom waves (unlike in all other modes), the losses decrease with increase in
frequency.

(Iskusetvennyye sputniki zemli. Spravka dlya radiolyubiteley-nablyudateley)
PERIODICAL: Radio, 1957, Nr 6, pp 14-17 (USSR)
ABSTRACT: The article presents information necessary for radio amateurs about
artificial Earth satellites and also some data about the influence of satellite
flight on the nature of signals received from it. The conditions of launching of
a satellite, the orbit, and the elements of orbit, including perigee, apogee,
orbit inclination, etc. , are explained in some detail. The belt of radio obser-
vation of a satellite is discussed. The Soviet satellite is expected to make
about sixteen circles around the Earth in 24 hours. Its orbit orientation is
such that practically any radio monitor living in a populated area of the Earth
will be able to observe the satellite twice or at leaut once a day. The sateUtte
will rotate around its own axis at the rate of a few revolutions per minute.
These rotations may cause fading because sometimes, the plane of the satellite
antennas may happen to be perpendicular to the direction of polarization of a
receiving antenna. Ordinary fading due to multipath arrival of radio waves to
the receiver will also take place. There will be, also, a special fading caused

by reflection of radio waves from the Earth's surface. Doppler effect is ex-
plained in detail. Satellite reappearance the next day may be shifted in time
for one hour or more due to the geophysical shift of the inclined orbit. It is
extremely important that radio amateurs record on tape signals from the satel-
lite and also the precise time of the signal. The 40 MC signal is more impor-
tant for orbit determination as it is less distorted in passing through the iono-
sphere.

TITLE: A Possible Trapping Mechanism of Charged Particles in a
Magnetic Field
PERIODICAL: Doklady Akademii nauk SSSR, 1960, Vol. 135, No. 6,
pp. 1354-1357

over to the phase space with the coordinates w V/a and u - agVa. The
2)3/2 d
u (U/W)
differential equation du/dw - W + 2-= - is obtained. An
U w + uw
analysis of the phase curves with respect to the isoclinal lines of this
differential equation is carried out. Schematical representations of the
changes in the direction of motion of the phase point are shown. These
changes are caused by the loss in kinetic energy. Herefrom, conclusions
are drawn as to the motion of the particle. The authors briefly deal with
the three-dimensional case in which a particle does not incide in the
equatorial plane, but arbitrarily. In this case the phase space is four-
dimensional: u, w, 1L%, dx%/dr, where -A is the meridian angle. From the in-
vestigation it follows that for any distance there exists a critical
velocity at which the energy loss leads to the trapping of the particle.
The authors finally state that this trapping mechanism is not the only one.
There are 3 figures and 5 Soviet references.
