Electromagnetically Induced Transparency‐Like on All‐Dielectric Metamaterials

Abstract

In this paper, an all‐dielectric metamaterial structure based on 3D printed is studied. The structure is composed of a 2 × 2 array of hollow cylinders. The electromagnetically induced transparency‐like (EIT‐like) effect is obtained by analyzing its transmission, and the mechanism of EIT‐like is analyzed by electromagnetic field distribution. The mechanism of EIT‐like is Mie resonance in the structure. The results demonstrate that the all‐dielectric metamaterial structure can obtain slow light effect, and the group index is >800. The research results have potential applications in slow light devices, sensing, and detection on microwave communication systems.
