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.

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
