Analysis of EM scattering from composite conducting-dielectric objects by time domain non-conformal VSIE
چکیده انگلیسی
To analyze the transient electromagnetic (EM) scattering from the composite structure containing inhomogeneous dielectric volumes and perfect electrically conducting (PEC) bodies efficiently and flexibly, a marching-on-in-time (MOT) based time domain non-conformal volume surface integral equations (TD-VSIE) method is proposed. The non-conformal volume integral equation scheme and surface integral equation discontinuous Galerkin (IEDG) method are combined to realize the non-conformal meshes discretization for composite objects. For some composite objects containing fine structure or inhomogeneous dielectric materials, notable reduction in the number of the unknowns can be obtained without sacrificing accuracy. Moreover, a hybrid mesh scheme is introduced to further improve the efficiency. Several numerical results are proposed to demonstrate the validity and flexibility of the proposed scheme.
