Abstract

We verify the feasibility of the proposed theoretical strategy for designing the broadband near-zero permittivity (ENZ) metamaterial at optical frequency range with numerical simulations. In addition, the designed broadband ENZ stack is used as meta-atoms to build functional nanophotonic devices with extraordinary properties, including an ultranarrow electromagnetic energy tunneling channel and an ENZ concave focusing lens.

摘要

我们通过数值模拟验证了在光学频率范围内设计宽带近零介电常数（ENZ）超材料的理论策略的可行性。此外，所设计的宽带 ENZ 堆叠被用作亚原子来构建具有特殊性能的功能纳米光子器件，包括超窄电磁能量隧道和 ENZ 凹面聚焦透镜。
