Abstract

A generalized higher-order finite-difference method (in which the time difference utilizes the symplectic integrator propagator and the spatial difference utilizes the discrete singular convolution) is proposed to analyze electromagnetic scattering from multiple targets. Numerical test results have demonstrated the higher stability and enhanced effectiveness of the proposed method when compared with the standard FDTD procedure. In addition, there are significant reductions in CPU time and memory space requirements when used with suitable meshes.
