In this paper, an electromagnetically induced transparency metamaterial simultaneously coupled with the incident electric and magnetic fields is designed and presented theoretically, whereas its reconfigurability, slow-wave effect, low-loss, and polarization insensitivity are analyzed and discussed principally. Based on the tunable solid-state plasma, there is a transmission peak with a 92.06% transmission at 0.544 THz in State 1 and a transmission peak with a 92.84% transmission at 0.7535 THz in State 2, thus achieving a frequency shift of 0.2085 THz. The maximum group delay, group index, and delay-bandwidth product in State 1 or 2, which are 723.7 ps or 494.7 ps, 1024.1 or 700.1, and 48.5 or 36.1, respectively, and the excellent slow-wave effects are discussed. In addition, the low-loss and polarization insensitivity are realized by rotating the split-ring resonators 180° and twisting the planar structure 90°. Considering the unique features of the designed metamaterial, it can be extensively applied to slow-light devices, communication, sensors, and nonlinear devices.

可重构电磁感应的透明超材料同时与入射电场和磁场耦合

本文从理论上设计并提出了一种电磁感应的透明超材料，同时结合了入射的电场和磁场，而对它的可重构性，慢波效应，低损耗和极化不敏感性进行了主要分析和讨论。基于可调谐固态等离子体，状态1在0.544 THz处有一个透射率为92.06％的透射峰，在状态2在0.7535 THz处有一个透射率为92.84％的透射峰，因此实现了0.2085 THz的频移。讨论了状态1或状态2中的最大群时延，群索引和时延带宽乘积分别为723.7 ps或494.7 ps，1024.1或700.1以及48.5或36.1，并讨论了出色的慢波效应。此外，通过将开口环谐振器旋转180°并将平面结构扭曲90°，可以实现低损耗和极化不灵敏性。考虑到所设计的超材料的独特功能，它可以广泛应用于慢光设备，通信，传感器和非线性设备。
