Excitation of an Electromagnetic Field in a Compact Nerve Fiber by a System of Filamentary Electric Currents

Resumo

We study the excitation of an electromagnetic field in a compact nerve fiber by a system of given filamentary electric currents, which are aligned with the fiber. In the case of a fiber consisting of several myelinated axons, equations for the scattering coefficients of the electromagnetic waves excited by such currents are obtained. On the basis of the solution of the corresponding equations, the total field due to these sources is found in the case of their location around the fiber. An approach is proposed for determining the filamentary-current amplitudes such that it ensures the formation of the required field pattern inside the nerve fiber. Numerical results demonstrating the possibility of selective field excitation in individual axons are presented.
