Abstract

A procedure for predicting electromagnetic fields propagating in a screened chamber is described. This is based on an adaptation of the time-domain finite-difference method. The procedure incorporates a technique to account for loss in the walls of a screened room. In addition an antenna model is described, which enables the coupling between electrically short dipoles to be predicted. Coupling experiments within screened chambers have been undertaken, however it is generally too difficult to adequately correlate predictions and measurement. This is due to the high Q of a screened chamber which results in small variations within the room causing major perturbations on antenna coupling. Experiments have been undertaken to investigate the effect of lining a chamber with coned anechoic absorbing material and tiled ferrite material. A review of numerical electromagnetic techniques is presented and various computer programs developed to implement these techniques are described.
