摘要：

A marching-on-in-time (MOT)-based volume-surface integral equation (VSIE) method is introduced to analyze transient electromagnetic scattering from the composite structures comprising perfect electrically conducting (PEC) bodies and inhomogeneous dispersive dielectric materials. A recursive convolution scheme is employed to deal with dispersive materials. The plane-wave time-domain (PWTD) algorithm is incorporated to accelerate the MOT scheme. In our examples, Debye, Lorentz, and Drude models are used to analyze the dielectric materials of the composite objects, respectively. Numerical results are given to demonstrate the accuracy and efficiency of the proposed scheme.
