We applied the Numerical Maxwell Model in 3 Dimensions (NMM3D) to radar scattering from ocean surfaces at L band. The formulation is based on the PMCHWT surface integral equation which uses separate Green's functions for air and ocean permittivities. The Sparse Matrix Canonical Grid (SMCG) is used to compute Method of Moments (MoM) solutions in conjunction with Rao-Wilton-Glisson (RWG) basis functions...
In vegetated surface scattering, the physical values of optical thickness and scattering albedo both increase with frequency. At C-band, because of the attenuation due to large optical thickness, the distorted Born approximation gives negligible values for the surface scattering term and double bounce term. Because of the smallness of these two terms, the distorted Born approximation gives results...
Recently, there is increasing interest in transient analyses of electromagnetic problems using the time-domain integral equations (TDIE) method. In order to use the TDIE for the micro-strip problems, several methods have been made previously to evaluate the time-domain Greenpsilas functions for layered medium. The Cagniard-de Hooppsilas method [2] is restricted to non-dispersive media and also becomes...
