Abstract

We proposed and numerically demonstrated an analog of electromagnetically induced transparency (EIT) in a Chinese character 王-shaped all-dielectric metasurface in the near-infrared region. Through asymmetric adjustment, the high transmittance EIT-like optical response of both single and double transparency windows can be realized. The EIT-like optical responses are clearly interpreted by the destructive interference between the bright dipolar moment and trapped magnetic dipolar mode through the asymmetric metasurface, and the dark dipolar moment causes the transparency window to split into two peaks. This all-dielectric structure shows a good application prospect in the field of refractive index sensors and slow-light transmission.
