Abstract :
We propose a simple THz wave plate based on the structured parallel metal plates. The fast and slow propagation properties for TE and TM waveguide modes bring in the controllable birefringence in wide frequency region. Using this optics, we experimentally obtained intense single-cycle THz pulse with the circular polarization.
