Abstract:

The electromagnetic analog computer used in the study and solution of Dirichlets problems in semispace was designed at the Institut of Geophysics, Bulgarian Academy of Sciences. The computers distinctive features include the following the integrals can be used for obtaining analogous expressions representing solutions of various boundary-value problems of semispace. The computer is of simple design. It is capable of determining measurements constants, i.e., proportionality coefficients between the effective value of induced voltages and values sought. An example is given of processing a potential field map.
