Abstract

The three-dimensional analysis of electromagnetic wave propagation using meshless time domain method is numerically investigated. The basic concept of the Meshless Time Domain Method (MTDM) is same as Finite Differential Time Domain (FDTD) method. In the discretizing process of the space, the shape function of Radial Point Interpolation Method (RPIM) is adopted. Thus, MTDM can be applied to the problem in the complex shaped domain easily. The result of computation show that the value of the damping rate decrease as the frequency increases. Moreover, the value of the damping rate depend on the shape of waveguide.
