Abstract
An efficient Finite Difference Time Domain approach is proposed for analyzing the propagation characteristics of 2-Dimensional planar scatter. An improved finite difference time domain method for the analysis of planar scatters is formulated. In order to solve an open initial boundary value problem, an absorbing boundary condition should be used as there are many forms of absorbing boundary conditions. We try to solve the scattering problem by using some absorbing boundary condition (ABC) at boundaries. Excitation pulses are used as sinusoidal and Gaussian. An illustrated example is also presented with the use of Mur's order boundary conditions. The proposed approach could be used easily in designing various waveguide structures. The scattering parameters for various geometrical structure are computed and results found consistent with either proposed values or values previously published. The strength of this approach to boundary conditions is also noticed in terms of the economical use of personal computer memory.
