Abstract:

In this study, single- and multilayer polarizers for terahertz radiation from a metal grid on a silicon substrate are analyzed through numerical simulation. Several variants of the polarizer design and the dependences of the polarizer characteristics on its design are obtained. The effects of the grid pitch, number of layers, and their mutual arrangement on the extinction coefficients and losses of the polarizer are numerically analyzed for the first time for choosing the optimal fabrication technology.

Keywords:
