Investigation of Circular Dichroism in Asymmetric Metamaterial
This article demonstrates asymmetric transmission in a chiral metamaterial across 7–11 GHz. When right-handed circularly polarized (RCP) and left-handed circularly polarized (LCP) waves impinge on this chiral metasurface, they exhibit different transmission characteristics. Non-reciprocity is observed when the RCP and LCP waves are incidents on the back side of the proposed metamaterial. Maximum circular dichroism is observed at 8.8 GHz for incident CP waves on the front side of the metamaterial. For waves impinging on the back side of the metamaterial, maximum circular dichroism is observed at 7.86 GHz and 10.06 GHz with the polarization plane rotated by 27.3° in the clockwise direction and 59° in the anticlockwise direction, respectively. Numerical simulations based on finite integration technique have been used to demonstrate circular dichroism. The proposed chiral metamaterial is a potential candidate for bio-sensing applications.
