Analysis of planar scattering of two dimensional structures using the finite- difference time-domain method

Abstract EN

Algorithms based on Finite Difference Time Domain technique for th< analysis of planar scatter structures are described.

The scattering parameter* for various geometrical structure are computed and the results founc consistent with either proposed values or values previously published.

W< try to solve the scattering problem by using absorbing boundary conditior (ABC) at boundaries.

Excitation pulses that used are sinusoidal anc Gaussian.

An example illustrating the use Mur’s first order boundary condition was introduced.

The proposed approach could be used easily ir designing various waveguide structures.
