Electromagnetic standing wave resonances in a periodically corrugated waveguide

摘要

Mode interaction in a periodically corrugated waveguide is studied in detail. A resonance of non-Bragg type, an electromagnetic standing wave resonance, is predicted in the waveguide. The resonance is caused by the interaction of modes of different space harmonics. The resonance interaction results in spectrum splitting and in the appearance of forbidden gaps (stop bands). In this connection the waveguide spectrum takes miniband character with densely spaced stop bands. Different spectrum features change significantly the electromagnetic properties of the waveguide.
