Basic Relations for an Electromagnetic Field in a Medium with Time-Varying Parameters and/or Moving Boundaries

An essential point for elaborating a common approach to the investigation of transient electromagnetic phenomena is the evolutionary character of such phenomena, and an initial moment, when the non-stationary condition starts, takes an important meaning. The introduction of the non-stationary initial moment is dictated in many cases by a necessity to separate the moment of “switching on” the field and the moment of the non-stationary behavior beginning. The non-stationary state, which starts at some definite moment of time, is accompanied by the appearance of a transient (non-harmonic) field. These so-called “transients” can ...
