Reflective Grating of Perforated Strips as a Frequency-Selective Surface

Reflective Grating of Perforated Strips as a Frequency-Selective Surface

Scattering of a plane monochromatic wave by a grating of metal strips periodically perforated by rectangular apertures has been studied. It is shown that such a grating provides a resonant reflection of an incident wave. An influence of geometrical dimensions of the grating upon the frequency and th...

A. Mospan, L. P. Scattering of a plane monochromatic wave by a grating of metal strips periodically perforated by rectangular apertures has been studied. It is shown that such a grating provides a resonant reflection of an incident wave. An influence of geometrical dimensions of the grating upon the frequency and the Q-factor of the reflection resonance has been considered. Spectral problem on searching the natural oscillation spectrum in the complex frequency range has been solved for a physical explanation of the reflection resonance. Numerical data for multi-layered filters with improved selectivity are presented. Исследовано рассеяние плоской монохроматической волны дифракционной решеткой из ме- таллических лент, периодически перфорированной прямоугольными отверстиями. Показано, что такая решетка обеспечивает резонансное отражение падающей волны. Рассмотрено влияние геометрических размеров решетки на частоту и добротность резонанса отражения. Для физи- ческой интерпретации эффекта полного отражения решена задача о спектре собственных коле- баний в комплексной области частотного параметра. Представлены результаты численного моделирования многослойных фильтров с улучшенной частотной избирательностью.
