Properties of the Solenoidal Inductor Surrounded by a Conducting Medium with a Dielectric Wall

Abstract

The analytical expressions for estimating the spatial distributions of quasi-static electric field are obtained for the near-field zone of single-layer solenoidal inductors surrounded outside by a thin dielectric wall and then by a medium with complex permittivity. It is shown that the presence of such a wall leads to the increase of self-capacitance, effective inductance and active resistance of inductor. The efficacy of active power transfer to the conducting medium increases in comparison with the case of absence of said wall.
