Abstract

We present experimental and finite-difference time-domain (FDTD) simulation studies on the THz Bragg stop bands carried out by using metal slit arrays positioned at the center of the air gaps in tapered parallel-plate waveguides (TPPWGs)[1]. The properities of THz stop bands determined in the simulations show excellent agreement with those observed experimentally. Recently, researchers have investigated the use of a TPPWG without a cylindrical silicon lens for improving THz coupling to the plate-separation air gap[2]. The TPPWG has many advantages when forming Bragg stop bands using slits such as strong THz coupling, easy setup, and long scan etc.
