Abstract
An optically transparent graphene-based wire-grid polarizer for operating at microwave frequencies (X band) has a glass substrate having multiple strips or layers of SOCldoped graphene. The strips are separated by portions of the glass substrate such that the strips are arranged in parallel. The SOCldoped graphene strips have a quasi-metallic quality allowing for the transmission of an electric field with horizontal polarization in the horizontal direction while reflecting the vertical portion of the electric field.
