Abstract

Metamaterial analogues of electromagnetically induced transparency (EIT) have recently attracted worldwide researchers to realize intriguing applications such as slow light devices and nonlinear optics [1, 2]. However, conventional EIT analogues could be generated only by the destructive interference between asymmetrically arranged radiative (bright) and non-radiative (dark) atoms to produce the sharp transmission window within the broad reflection band. In this work, we studied a new way to achieve EIT-like spectral properties from a single self-complimentary meta-atom (SCM) by integrating cut-wire (CW) pair with a pseudo-complimentary cut-wire (p-CCW) structure within a unit cell. Different from the conventional EIT analogues, electric field (E-field) was highly enhanced and focused at edges of the hole and EIT-like properties are generated in the proposed SCM structure.
