Abstract-Analog of Electromagnetically Induced Transparency at Terahertz Frequency Based on Bilayer-Double-H-Metamaterials
Yuee Wang, Zhi Li, Fangrong Hu, http://iopscience.iop.org/article/10.1088/1361-6463/aa9ba0/pdf We design a bilayer-double-H-metamaterials (BDHM) composed of two layers of metallic and two layers of dielectric to analog a spectral response of electromagnetically induced transparency (EIT) at terahertz frequency. By changing the incident angle, the BDHM exhibits the EIT-like spectral response. The tunable spectral performances and modulation mechanism of transparent peak are theoretically investigated using a full-wave electromagnetic simulation software. The physical mechanism of the EIT-like effect is based on the constructive and destructive interference between the induced electrical dipoles. Our work provides a new way to realize the EIT-like effect only by changing the incident angles of metamaterials. The potential applications include tunable filter, sensor, attenuator, switches, and so on.
