Abstract

A comparison between the measured and theoretically predicted site shielding factor (SSF) of a thin finite-width screen is made. The SSF, which expresses the additional attenuation caused by an obstacle on the propagation path, is measured along a cylindrical arc behind the screen at a frequency of 50 GHz. The measured SSF curves compare very well with those predicted by a theoretical model, which uses the uniform geometrical theory of diffraction (UTD) and includes corner diffraction. The same holds for the measured and theoretically derived time-domain results, which clearly demonstrate the ray behaviour of the diffracted fields, as assumed in the UTD.
