A method of moments (MoM) analysis has been developed for the calculation of electromagnetic scattering from and the natural resonances of a dielectric body of revolution (BOR) embedded in a layered medium (the half-space problem constituting a special case). The layered-medium parameters can be lossy and dispersive, of interest for simulating soil. To make such an analysis tractable for ultra-wideband (short-pulse) applications and the calculation of natural resonances, we use the method of complex images to evaluate Sommerfeld-type integrals, characteristic of the dyadic Green's function of a layered medium. Example wideband scattering results as well as results for the fundamental natural resonant frequency are presented for a model plastic mine. Of special interest here is the influence of the background soil environment (e.g., water content, covering snow layer) on the ultra-wideband (UWB) scattering signature and the late-time resonances of plastic mines. ©2003 Copyright SPIE - The International Society for Optical Engineering.
