Abstract :
We present two polarizing elements designed to produce linear and circular polarization for broadband, pulsed THz waves. The linear polarizer is made out silicon wafers arranged at Brewster´s angle and the circular polarizer is made out of a silicon prism using total internal reflection differential phase-shift effect.
