Transverse-magnetic electromagnetic waves in a waveguide with space-time multiperiodically modulated filling

Abstract

Propagation of electromagnetic TM waves in a waveguide filled with space-time multiperiodically modulated nonmagnetic dielectric filling is discussed. The analytic expressions for the TM filled are obtained on the assumption of a small modulation indexes of the filling. The frequency of the "strong interaction" between the signal wave and the modulation wave is found.
