(Author's abstract. In this paper, an analogy is broup,I+t c..t bttveen the
field equations and the equations characterizing the relationships between
voltagec and currents in a model Ezasples are given of drawing up models for
the solution of problems connected with the propagation of electromagnetic
waves in wave guides and with the study of the electromagnetic field in cav-
ity resonators).
The accurate solution of some boundary problems involved in the study of
processes occurring in the electromagnetic field in a two-dimensional, and
especially a three-dimensional space, with certain boundary conditions is very
difficult in practice
The use of the finite difference method for the solution of equations
describing, these phenomena involves the aolrti,n of merry equations with many
ununoens, a'difficult and time-ionsoing process.
it has 'yen shown tnt acwAsw pro;, a may be solved approximateiy by toe
electrical modeling method, using models-developed by L. I. Gutenmakher

tthis problem was discussed in a paper read by the suthor at the All-Union
Co fexere on Electrical Modeling in 1949).

The desired components of the field under study can be found by measur-
ing the voltage at the junction points of the model. But the distribution
of voltage at the junction points of the model characterizes the scalar field
of the space. Therefore, if the model is used to study a vector field, the
latter must be resolved into components with respect to the axes of the co-
ordinate system in such a manner that the numbers used to measure the compo-
nents of the field vectors may be scalar. Consequently, in the solution of an
actual vector field problem, one must perform as many cycles of voltage meas-
urements at the jun
