Abstract:

According to Andersen’s high order curl vector basis function, a set of higher order hierarchical basis functions is proposed for electrical field integral equations solved with the method of moments. Combined with the multilevel fast multipole method (MLFMM) the basis function is used to accelerate matrix vector product in
analyzing electromagnetic scattering and radiation of electrical targets. A hierarchical grid iterative algorithm based on the generalized minimal residual (GMRES) algorithm is proposed to improve computation efficiency. Numerical results show that this method is effective in dealing with electromagnetic scattering.
