摘要：

Linear-to-linear polarization conversion of electromagnetic wave has application in various fields including communications, imaging and sensing. Available polarization control devices enabled by metasurfaces are limited in bandwidth, efficiency and acceptance angle. Herein, a reflective half-wave mirror composed of T-shaped resonators is proposed and experimentally evaluated. Measured results show a bandwidth of 95% and 100% around a center frequency of 0.7 THz for the normal and 45 angle of incidence. The measured results agree well with the simulation. An average polarization conversion ratio (PCR) greater than 80% is observed across 0 degrees to 45 degrees incidence angles.
