Abstract:In this paper, a Janus metastructure device (JMD) is proposed. The JMD design introduces asymmetric structures, which leads to the generation of analogous quantum optical effects when light is incident at large angles. Specifically, forward electromagnetic‐induced transparency (EIT) and backward narrowband absorption (NA) are achieved when light is incident along different directions, displaying Janus characteristics in the forward and backward directions. Additionally, the operating frequency of JMD can be co… Show more
