In this paper, PO solution of electromagnetic scattering of anisotropic coating target under point source excitation has been derived. Firstly, According to the tangent plane approximation in the PO field, the high frequency scattering problems of point source excitation infinite plane model coated anisotropic medium can be solved specifically. Secondly, we can expand any scattering wave field including...
The high-frequency scattering of an electrically large target can be well approximated as a sum of response from individual scattering centers. The scattering center model can provide a concise and physically relevant description of the target radar signature. We use the attribute scattering center model to represent the targets' high frequency back scattering. In this model, the backscattered field...
In this paper, we present a parallel implementation of the Multilevel Characteristic Basis Function Method (MLCBFM) for the analysis of the scattering from electrically large rough surfaces. The Multilevel Characteristic Basis Function method is a natural extension of the conventional mono-level CBFM, which addresses the issues of high computation burden and memory requirement associated with this...
This paper presents an efficient algorithm combining the stabilized biconjugate gradient fast Fourier transform (BCGS-FFT) method with an improved discrete complex image method (DCIM) for electromagnetic scattering from electrically large objects in both lossless and lossy multilayered media. The required spatial Green's functions obtained by the improved DCIM are accurate both in the near- and far-field...
