The resonant scattering of electromagnetic plane wave on a perforated screen with circular below-cutoff holes in a periodic cell is investigated. Several holes on a period are found to qualitatively change the screen frequency response. Along with the total transmission of the exciting field in a on...

| description | The resonant scattering of electromagnetic plane wave on a perforated screen with circular below-cutoff holes in a periodic cell is investigated. Several holes on a period are found to qualitatively change the screen frequency response. Along with the total transmission of the exciting field in a one wave frequency bandwidth, the total reflection mode is also possible. To explain the nature of such behavior, the perforated screen is considered as an open periodic resonator, and its eigenoscillations are analyzed. On the strength of symmetry principles, the general peculiarities of spectra formation for regular periodic structures are determined, the existence of real valued eigenfrequencies converging to zero frequency being particularly found. The oscillations determining the resonance behavior are found too, their space pattern studied. |

A. Perov, A. O. Senkevich, S. L. The resonant scattering of electromagnetic plane wave on a perforated screen with circular below-cutoff holes in a periodic cell is investigated. Several holes on a period are found to qualitatively change the screen frequency response. Along with the total transmission of the exciting field in a one wave frequency bandwidth, the total reflection mode is also possible. To explain the nature of such behavior, the perforated screen is considered as an open periodic resonator, and its eigenoscillations are analyzed. On the strength of symmetry principles, the general peculiarities of spectra formation for regular periodic structures are determined, the existence of real valued eigenfrequencies converging to zero frequency being particularly found. The oscillations determining the resonance behavior are found too, their space pattern studied. Исследованы режимы резонансного рассеяния плоской электромагнитной волны на перфорированном экране с двумя круглыми запредельными отверстиями в периодической ячейке. Обнаружено, что наличие нескольких апертур на периоде качественно изменяет АЧХ экрана. Наряду с режимом полного прохождения поля возбуждения в одноволновом диапазоне возможна реализация режима полного отражения. Для объяснения природы последнего исследованы собственные колебания экрана как открытой структуры – периодического резонатора. Исходя из законов симметрии установлены общие принципы формирования спектра регулярных периодических структур и, в частности, существование реальных собственных частот, сгущающихся к нулевой частоте. Выявлены колебания, определяющие резонансное поведение, и исследована их пространственная структура.
