Electromagnetic scattering from conducting combination target of body of revolution (BoR) and arbitrary structure is analyzed using the integral equation domain decomposition method (IE-DDM). In non-conformal IE-DDM framework, the target is divided into the BoR sub-domain and non-BoR sub-domain according to geometrical feature, where the BoR and RWG basis functions are used respectively. To realize...
In this paper a numerically efficient strategy for solving the scattering problems from multiple Bodies of Revolution(BoR) is described. This approach is based on the method of moment(MoM) expand by BoR basis function. By using a current coefficient transform algorithm, the BoR halfglobal basis function is applied in multiple objects problems. As a result, the CPU time is reduced compared with RWG...
In this paper, the integral equation - fast Fourier transformation (IE-FFT) with grid-robust higher order vector basis functions is presented. The magnetic field integral equation (MFIE) is used for solving scattering from three-dimensional closed perfectly electric conductor (PEC). Conformal mesh is required for traditional basis function based on common edges between adjacent elements. This is very...
An overlapped domain decomposition method with congruent sub-domains is developed for electromagnetic surface integral equations. Based on congruent sub-domains, the proposed method creates a set of uniform mesh such that all the self-matrices on the congruent sub-domains share an interior-interior sub-matrix, which can reduce the memory requirement and the matrix filling time, intensively, especially...
