A Fast Time Domain PMCHW Equations for Predicting Transient Responses of Dielectric Objects

The time domain discontinuous Galerkin Poggio-Miller-Chang-Harrington-Wu integral equation method based on an improved marching-on-in-degree scheme is proposed for accelerating the simulation of the transient scattering responses of arbitrary shaped homogeneous dielectric objects. A combination of three weighted Laguerre polynomials is set as new temporal basis functions to derive the final equations. Therefore, the entire solution process can be accelerated. Some numerical examples are given to validate its efficiency and accuracy.
