SPECTRAL PROPERTIES OF A RECTANGULAR WAVEGUIDE SECTION WITH TWO UNEVEN RECTANGULAR POSTS
Abstract
The nature of the resonances of total reflection being provided
by a waveguide section with two uneven rectangular posts arranged
symmetrically along the broad wall of a rectangular guide
was investigated. The study was performed within the spectral
theory of open waveguide resonators. Total reflection resonances
were interpreted as the result of excitation of two natural
oscillations. The behavior dynamics in the complex plane was
examined for the natural oscillations while varying all the geometric
parameters of the section. Diffraction and spectral characteristics
were compared. The contribution of each natural
oscillation into formation of the frequency response was estimated.
It was shown that the position of each reflection resonance
and its quality factor were evaluated with a high accuracy
by the complex frequency of one natural oscillation participating
in its formation.
