On the character of increase in the field upon resonance excitation of a waveguide

Аннотация

The problem of excitation of an anisotropic media-filled waveguide at critical frequencies is considered. An example of a dispersion curve with two rather than one or three singular points is presented. The possibility of excitation of back waves is studied. The character of the increase in the field upon resonance excitation of a waveguide is considered.
