Analysis and Simulation of Twist Reflector with Different Incident Angles

Twist reflector has a large significance for many systems. Notably, much work so far in the literature has focused on the basic concept and structure designing of twist reflector. There are relatively few studies devoted to performance analysis of twist reflector with different incident angles. Hence, it is necessary to investigate detailed the effect of incident angle on the performance of 90° twist reflector. In this paper, analysis and simulation of polarization twist at different angles of incidence are presented firstly, and good performance can be achievable for polarization twisting when incident angle (θ) is unequal to 0° and the grating orientation (φ) is 45°.
