Abstract

In this study, a reflecting terahertz (THz) metamaterial polarization converter consisting of three hexagonal rings with two cuts is presented. The polarization converter has an almost perfect wideband linear to circular (LTC) polarization conversion over the bandwidth of 1.58-1.87 THz (ie, 0.29 THz) with AR≤ 0.47 dB, Δφ= n90±5 and e= 1±0.01. Besides, the proposed polarization converter has an almost linear to linear (LTL) polarization conversion around three frequencies such as 1.05 THz, 1.19 THz and 1.31 THz.
