TRANSIENT ANALYSIS OF ELECTROMAGNETIC FIELD PROPAGATION IN THE VICINITY OF MILLIMETRE WAVEGUIDE STRUCTURES WITH AN EFFICIENT FINITE‐DIFFERENCE TIME‐DOMAIN TECHNIQUE Available to Purchase

The FDTD approach is rapidly becoming one of the most widely used computational methods in electromagnetics. It is a marching‐in‐time procedure which simulates the continuous actual waves by sampled data numerical analogues propagating in a data space stored in a computer. Thus it leads to a complete understanding of near fields and transient effects. In this paper, the study of the propagating modes and the calculation of the energy forced in the interior of a terminated waveguide is performed with an iterative FDTD technique. Results are obtained and compared with the theoretical ones. Their agreement is almost perfect.
