Propagation of transverse-magnetic waves in a waveguide with anisotropic and magnetoactive modulated insert eurocon2009

摘要

Propagation of transverse-magnetic (TM) waves in the waveguide with arbitrary cross section, filled with periodically modulated anisotropic and magnetoactive medium is considered. The differential equation for the potential of TM field is found from the Maxwell equations. This equation is solved with help of method, developed in our earlier articles. The analytical expressions for the magnetic and electric vectors of the TM field are found in the region of weak interaction between the signal wave and the modulation wave in the first approximation for small modulation indexes of the insert. The frequency of strong (resonance) interaction between the signal wave and the modulation wave is expressed in an analytic form.
