Domain Decomposition Method Based 3-D Electromagnetic Simulation Research

This paper introduces a regional decomposition electromagnetic simulation method, first of all, the antenna structure module is divided into regions to obtain a plurality of subdomains; for each subomain, a tetrahedral mesh is utilized to dissect said subdomain to obtain a plurality of tetrahedra; for each tetrahedron, according to the position of the vertices of the tetrahedron and the length of the edges, a vector basis function is obtained for each edge of the said tetrahedron; for each edge, a vector basis function is obtained for each edge, and a vector basis function for each subdomain is obtained for each edge. function for each edge and the two-spin electric field fluctuation equation of the subdomain to which the edge belongs, calculate the tetrahedron to which the edge belongs. For each edge, the electric field value at any point in the tetrahedron to which the edge belongs is calculated using the corresponding vector basis function of the edge and the double spin degree electric field fluctuation equation of the subdomain to which the edge belongs. Compared with the conventional finite element method (FEM), the method proposed in this paper shows a significant improvement in terms of computation time and required storage space efficiency.
