A THIN STEP-BENDED CONDUCTOR IN THE RECTANGULAR WAVEGUIDE CROSS-SECTION PLANE AS A SIMPLE REFLECTOR
摘要
Simple geometries of practically feasible units placed in the cross-section plane of a rectangular waveguide are analyzed, which are capable of supporting narrow-band full reflection resonances. The elements represent thin step-bended conductors connecting two opposite walls of a waveguide. They can be regarded as a special kind of two-aperture irises which can be placed, for example, between the waveguide flanges. The resonance effect supported by such structures is based on the interference interaction of the iris eigen-mode fields with two L-shaped apertures. The reflection resonance frequency and Q-factor are controllable over a wide range through changing the position and height of the stepped bend. Situations are analyzed when a perfect step-bended conductor provides for a resonance characterized by a practically zero width of the stop band. Such a nontrivial 3D waveguide unit loaded on feeding sections is capable of supporting eigen-mode oscillations with no radiation losses. Results of computer simulations and its experimental verification are presented.
