Abstract
The present disclosure relates to a domain decomposition method and system for electromagnetic simulation. The method includes: dividing an antenna structure model into multiple subdomains, where each of the subdomains corresponds to a structure in one to-be-simulated array antenna; subdividing each of the subdomains by a tetrahedral network to obtain multiple tetrahedrons; obtaining a vector basis function of each edge of each of the tetrahedrons according to vertex positions and lengths of the edges of the tetrahedron; and calculating an electric field value and a magnetic field value of any point in a tetrahedron to which each of the edges belongs using a vector basis function corresponding to the edge and a double curl electric field wave equation of a subdomain to which the edge belongs.
