Abstract

The two-dimentional meshless time-domain method (2D-MTDM) was used to simulate the electromagnetic wave propagation phenomena in complex-shaped waveguides considering the influence of metals and to numerically investigate the relation of the dispersion medium with the attenuation rate. The simulation results suggest that the waveguide with grooves is strongly affected by the frequency of the propagating wave than the waveguide without grooves because the wave propagating in the waveguide with the grooves penetrates deep into the metal compared with the waveguide without grooves. The transmission loss for the curved waveguide is greater than that for the straight waveguide.
