Electromagnetic fields in a flat inductor system with massive bifilar coils

Abstract

For the first time, a flat inductor system was proposed, where a multi-turn inductor solenoid is placed between the branches of a massive bifilar coil, which reduces the scattering of electromagnetic energy with the minimum possible influence of its field on electromagnetic processes in the inductor solenoid. Within the accepted assumptions about the rather high conductivity of bifilar windings, which is practically realized in the region of correspondingly high operating frequencies of electromagnetic processes, the calculated relations for analysis and numerical evaluation of excited fields and currents in the proposed inductor system are found. It is obtained that the efficiency of current excitation in bifilar windings weakly depends on the distance between the inductor and the bifilar, the radial distribution of the induced current is almost uniform and the influence of the excited magnetic field on the processes in the inductor should be quite insignificant. The results of the analysis and calculations for the experimental model allow us to conclude on the practical performance of the proposed inductor system, excited by a flat circular solenoid placed between the massive windings of the bifilar.
