Abstract :
The total reflection resonances that take place at the excitation of a two-slot resonant iris in rectangular waveguide, are discussed. Considering the iris as an open-resonator-waveguide structure, the pair of natural oscillations responsible for such resonances was numerically found and investigated. Some numerical results and experimental data for two-slot irises are presented. It is pointed out to a parallel between rejection resonances in two-slot irises and "locked"-mode resonances in multimode waveguide structures.
