The interaction of two coherent counter propagating TE (transverse-electric) and TM (transverse-magnetic) electromagnetic waves with different initial phases in the absorbing plate placed in the regular ideal wave... The interaction of two coherent counter propagating TE (transverse-electric) and TM (transverse-magnetic) electromagnetic waves with different initial phases in the absorbing plate placed in the regular ideal waveguide is considered. The losses of energy of TE and TM waves in the absorbing plate are calculated. Some features of tunnel interference in the absorbing plate in the waveguide are revealed. It is shown that the losses of energy strongly depend on the various parameters describing the interaction of the counter propagating waves. Definitely choosing the parameters we can control the electromagnetic processes in this case. 展开更多
