Bingkang Chen, Benqing Gao, Chengcun Ge, Jinglan Li

Abstract


Characteristics of wave propagation in some time-varying media have been studied. Using the separation of variables and hybrid method, accurate solutions of electromagnetic waves are obtained when and are monotone and periodic functions with respect to time. Furthermore, the classes of  and on which wave equation has analytical solution are studied and listed. In time-varying media conditions, some time-varying parameters such as frequency shift, change of phase velocity, wave impedance are also discussed. The examples and rationale for the results are given.
