Abstract

Electromagnetic field transformation in the media with continuously time varying conductivity is studied by solving Volterra integral equation for the field. Exact solutions for the fields are obtained for a continuous temporal variation of the medium conductivity from one constant value to another, and for time-splashing conductivity. Their analytical and numerical analysis shows features of wave splitting on the non-abrupt temporal step of conductivity for the former case, and spatial field re-distribution for the latter
