The high quality resonance is achieved by excitation of the trapped-mode in array with two concentric metal rings in a cell on a silicon substrate. Optical activation of the silicon substrate permits to switch off the transmission band.engAcesso AbertoSuperfícies Seletivas de FrequênciaRessonância de alto fator de qualidadeDispositivos de micro-ondasMicrowave switchable frequency selective surface with high quality factor resonance and low polarization sensitivityArtigo de Periódico
