Based on the method of physical optics (PO) and the method of ray tracing (RT), we analyzed the near-field primary scattering of the panels, the near-field secondary scattering between the facets, the near-field composite scattering between facets and rough sea surface. Simultaneously, we calculated the near-field and far-field scattering versus incident angles by a dihedral made of two orthogonal...
The electromagnetic scattering of conductor plate coated with multilayer medium is investigated based on the physical optics (PO) theory and the principle of equivalent impedance boundary condition (IBC). Compared with the multilayered plate coated with right-handed medium, the radar cross section (RCS) of plate composed of metamaterial and right-handed medium has a reduction of 5.76dBsm in the mirror...
This paper presents a theory method to calculate and analyze the scattering near field from some simple and complex targets, using high-frequency approximation. By calculating the near-field RCS of some simple and complex targets based on the SCTE (scattering from complex targets and environments) system, the results show that there are much difference between the near field and the far field. And...
The high-frequency method in conjunction with impedance boundary condition is one of effective tools in analyze the far or near field of EM scattering by electrically large coated object. The far field RCS of coated plate calculated in the paper shows agreement with experimental results , and the differences between near field RCS and the far field RCS concludes that the near field scattering must...
