Electron Cyclotron Heating (ECH) and Electron Cyclotron Current Drive (ECCD) are attractive options for improving the performance of fusion reactor plasmas. Oblique launch of the electromagnetic wave to magnetized plasma demands specified elliptical polarization for high mode purity of ordinary or extraordinary waves. Polarizers for high power millimeter waves have been developed using corrugated all-metal mirrors. Structure analysis of polarizers will be important for high power, high frequency, and long pulse ECCD system in the next generation of fusion devices.
