We consider the accuracy improvement of the high frequency scattered fields from the 3-D convex scatter by the Fock current and the incremental length diffraction coefficient (ILDC) technique. We propose the numerical contour deformation method to calculate the Fock currents, and treat them in the scatterer's lit and shadow regions, separately. Then, by adopting the ILDC technique, high frequency...
In this paper, we focused on the study of electromagnetic (EM) wave propagation in a particular anisotropic medium—Infinity-anisotropic (IA) metamaterial. IA metamaterials, which include infinity index-anisotropic and infinity loss-anisotropic metamaterial, have the ability to suppress the diffraction limit of EM wave. Thus the deep subwavelength wave could propagate in the IA metamaterials without...
