“…This method requires finer grids for approximation, thus leading to a heavier burden on the FFT. Shortly after this, the pre-corrected FFT (p-FFT) that had been used to electrostatic problems [14] was extended to dynamoelectric problems [15], [16]. In the p-FFT, the projection is obtained by matching the electromagnetic potentials rather than the high order multipole moments.…”

In this paper, a novel realization of the Integral Equation in combination with the fast Fourier transform for the CFIE is established by Fitting both the Green's function and its Gradient onto the nodes of a uniform Cartesian grid. The new method has been compared with several existing popular FFT-based methods, including the AIM, the IE-FFT, and the p-FFT. The accuracy of the proposed method is significantly higher than other FFT-based methods, and the method is not sensitive to both the grid spacing and the expansion order. The outstanding merit of the proposed method is that the fitting procedure is independent of the basis functions. Therefore, when the higher order basis functions would be adopted in the method of moments, only one fitting procedure for the Green's function and its gradient on a basis function support is needed to meet all of basis functions defined on this support. Some numerical examples are provided in this paper to demonstrate the accuracy and efficiency of the proposed method.

Abstract-In this paper, we apply the parallel method of moments (MOM) to solve the Electric and Magnetic Current Combined Field Integral Equation (JMCFIE) for scattering by large, three-dimensional (3-D), arbitrarily shaped, homogeneous dielectric objects. We first derive the JMCFIE formulation which produces well-conditioned matrix equation when the MOM with Galerkin's type testing and RaoWilton-Glisson (RWG) functions is applied. We then develop a parallel conjugate gradient (CG) method on personal computer (PC) clusters using message passing interface (MPI) for solving the matrix equation obtained with JMCFIE. The matrix is decomposed by the row and stored in distributed memory of the node. Several numerical results are presented to demonstrate the accuracy and capability of the proposed method.

Abstract-In this paper, the Parallel Finite-Difference Time-Domain (FDTD) method based on MPI (Message Passing Interface) is applied to analyze the EMC problems of the electrically large platforms accurately and quickly, which is a full-wave numerical method. The MPI library and domain decomposition method are applied to implement the Parallel FDTD method, so that the computation resource is expanded. The method can analyze the EMC problems by modeling the electrically large platforms accurately. Then the network theory is introduced to compute the isolation between antennas combined with the Parallel FDTD method firstly, which avoids the complexity of sweeping frequency and reduce the computing time greatly. Numerical results show that the method is correct and efficient. Finally, the EMC problems of antennas mounted on electrically large platforms are analyzed and some useful conclusions are obtained.
