Experimental validation of a stable method of moments procedure in time domain for the scattering from arbitrarily shaped conducting bodies

In this paper, numerical results obtained by the application of a stable ma rching-on-in-time solution scheme of the electric held integral equation ar e compared against experimental data, assuming as a testing case that of el ectromagnetic scattering from perfectly electrically conducting bodies. The experiments have been performed in an electromagnetic pulse hardware simul ator, reproducing plane wave illumination conditions. The surface current d ensities induced on the metallic bodies have been measured by means of prob es sensitive to the tangential magnetic fields. The measured current densit ies have therefore been processed in order to eliminate the effects of the measuring instrument chain. Near-field measurements have been performed by using probes sensitive to the electric field. Experimental data show a good agreement with numerical predictions.
