Short-pulse scattering from a dielectric BOR buried in a lossy layered medium
A method of moments (MoM) analysis has been developed for ultra-wideband (UWB) electromagnetic scattering from a dielectric body of revolution (BOR) embedded in a layered medium. The layered-medium can be lossy and dispersive, of interest for simulating soil (and/or a covering snow layer). To make such an analysis tractable, we use the discrete complex image technique to evaluate Sommerfeld integrals, characteristic of the Green's functions for a layered medium. Example results are presented for a model plastic mine, including a comparison to the results obtained for a perfectly electric conducting (PEC) mine with the same geometry.
