Using The Integral Equation Method Of Moments Calculated Precisely Ideal Target Electromagnetic Scattering Of Conductors

The accurate and fast calculation of electromagnetic scattering problems of the ideal conductor has always been an intensive research in computational methods for electromagnetics. When we use integral equations to solve the ideal conductor of electromagnetic scattering problems, It will generate singularity when the triangle have the common nodes. The accurate calculation of them is very important because they are critical to ensure that the impedance matrix of morphological stability. This paper use a new algorithm to deal with the kind of singularity, It get higher accuracy in the analysis of electromagnetic scattering problems on the goals of an ideal conductor.First, this article details the ideal conductor surface integral equation, the basic principle and the solving steps of the method of moments and RWG basis function which Based on planar triangulation.Then, the article describes a solution procedure based on the RWG basis functions Galerkin surface integral equation method.It Provide a theoretical basis for this method.Finally, this article use an accurate computational method to deal with an ideal conductor of the singular integral in the frequency domain surface equation. This method is based on the method of moments,first It use parameter coordinate transformation and the relative coordinate transformation to decompose the integration region. And then use Duffy coordinate transform to eliminate the singularity of the process of solving the electric field integral equation which the field and source of triangular elements in the same plane and in the adjacent (with have a common edge or a node),In the process of solving frequency-domain magnetic field integral equation,and it eliminate the singularity of which the field and source of triangular elements in the adjacent (with have a common edge or a node). Especially for some objects which have irregular shape,effectively solve a range of issues such as the matrix behavior is poor,the singular integral converge is slow and even does not converge.This research work of this article provides an accurate method to solve complex three-dimensional target body with a fine split and also made the foundation for In-depth study of the dielectric and metal media portfolio objectives.
