The Use of an Equivalent Circuit to Describe Electromagnetic Processes in the Tissues of Living Bodies at the Cellular Level.

This paper is concerned with the development and numerical implementation of a mathematical model for studying electromagnetic processes in body tissues at the cellular level under the action of sine-wave voltage of different frequencies. The basis of the model is an equivalent circuit that takes into account the structural features of one of the most elaborate skeletal muscle tissues. The model allows describing the electromagnetic processes occurring in the muscle tissue at the level of its individual cells under the action of sine-wave voltage of differing frequency. The model adequacy is confirmed by comparing the results of calculations of the frequency dependence of the modulus of the complex permittivity and experimental data. The results of calculations when the electrodes are located along the muscle tissues give an idea of the conductivity of the epimysium and the muscle cells themselves, which, in turn, indicates the level of "activity" of the muscle tissue.
