一种基于电耦合的电磁诱导透明超材料
Novel metamaterial with electromagnetic induced transparency based on electric coupling
摘要
Abstract
A high transmission metamaterial of electromagnetical induced transparency (EIT) was designed based on electric coupling between two resonant structures which was obtained by the electromagnetic excitation of bright mode on dark mode.At the same time,these two modes operated at the same frequency but with different Q factors.Because of the short distance and high electric coupling between the bright mode and dark mode,a novel EIT phenomenon can be achieved at the same resonant frequency.Finally,a transparency window was achieved at 5.31 GHz with a transmission level as high as 0.85,whose working mechanism was analyzed by the surface currents distributions,the electric and magnetic field distributions.The proposed EIT metamaterial offers a latent application value to produce antenna housings with high performance.关键词
