“…All of the aforementioned methods rely on continuous and conformal meshes. A discontinuous Galerkin (DG) surface integral equation based on non-conformal meshes has been developed in recent years [12][13][14][15][16][17][18][19][20][21][22][23], which allows for surface partitioning, and each partitioned subsurface (sub-region) can be meshed independently. In this study, not based on integral equation methods, a processing technique for different mesh sizes at the boundary between two parts is presented using the PO method.…”

In electromagnetic (EM) simulation, conventional triangular patches are implemented to discrete the surface of the conducting objects. Based on the Rao-Wilton-Glisson (RWG) basis function and the continuity of the surface current across the boundary with different mesh sizes, the EM scattering of the conducting objects are presented. The radar cross section (RCS) are acquired for conducting objects by the physical optics (PO). The numerical results can be compared with those from the commercial software (Feko), which indicates the accuracy and effectiveness of the method in this letter.
