SPECTRAL PROPERTIES OF A RECTANGULAR WAVEGUIDE SECTION WITH TWO UNEVEN RECTANGULAR POSTS

The nature of the resonances of total reflection being providedby a waveguide section with two uneven rectangular posts arrangedsymmetrically along the broad wall of a rectangular guidewas investigated. The study was performed within the spectraltheory of open waveguide resonators. Total reflection...

P. Prikolotin, S. A. Steshenko, S. O. Kirilenko, A. A. The nature of the resonances of total reflection being providedby a waveguide section with two uneven rectangular posts arrangedsymmetrically along the broad wall of a rectangular guidewas investigated. The study was performed within the spectraltheory of open waveguide resonators. Total reflection resonanceswere interpreted as the result of excitation of two naturaloscillations. The behavior dynamics in the complex plane wasexamined for the natural oscillations while varying all the geometricparameters of the section. Diffraction and spectral characteristicswere compared. The contribution of each naturaloscillation into formation of the frequency response was estimated.It was shown that the position of each reflection resonanceand its quality factor were evaluated with a high accuracyby the complex frequency of one natural oscillation participatingin its formation. Исследована природа резонансов полного отражения, формируемых волноводной секцией с парой разновысоких прямоугольных штырей, симметрично расположенных вдоль широкой стенки прямоугольного волновода. Исследование проведено в рамках спектральной теории открытых волноводных резонаторов. Резонансы полного отражения интерпретируются как результат возбуждения в резонансной секции собственных колебаний комплексной частоты. Изучена динамика поведения частот собственных колебаний на комплексной плоскости при изменении всех геометрических параметров секции. Сопоставлены дифракционные и спектральные характеристики. Проанализирован вклад собственных колебаний в формирование частотной характеристики. Показано, что положение каждого резонанса отражения и его добротность определяются с высокой точностью по значению комплексной частоты одного из собственных колебаний, принимающих участие в его формировании.
