Abstract

A tapered parallel-plate waveguide was simulated using finite-difference time-domain method to vary the opening angle and its effect on the transmitted terahertz electric field amplitude and spectra. TE and TM mode gaussian terahertz beams were used as light source. The highest amplitude and spectra power was obtained using a 10 degree opening angle for both TE and TM modes. The TE mode terahertz source also showed higher electric field amplitude using the simulated waveguide structure. A cut-off frequency at 240 GHz was observed with the TE mode terahertz source.
