—Wave scattering from two-dimensional (2-D) random rough surfaces up to several thousand square wavelengths has been previously analyzed using the sparse-matrix canonical grid (SMCG) method. The success of the SMCG method highly depends on the roughness of the random surface for a given surface area. In this paper, we present a multilevel expansion(More)
A numerical method for transient electromagnetic scattering by uniformly moving target is proposed. Two reference systems are adopted: one is attached on the radar platform while the other is fixed on the target. Finite Difference Time Domain (FDTD) method is employed to analyze the scattering in the target system. Lorentz transform is exploited to transfer(More)
The frequency and polarization dependence of scattering by the densely packed spherical particles is rigorously studied with the Monte Carlo simulations for solving both 2-and 3-dimensional Maxwell's equations at microwave frequencies. Numerical simulation solutions indicate that the frequency dependence of densely packed sticky small particles is much(More)
—An efficient algorithm for wave scattering from two-dimensional lossy rough surfaces is proposed. It entails the use of a single magnetic field integral equation (SMFIE) in conjunction with a multilevel sparse-matrix canonical-grid (MSMCG) method. The Rao–Wilton–Glisson (RWG) triangular discretization is adopted to better model the rough surface than the(More)
