| Abstract: | A method of high-order basis function is constructed by the theory of the best uniform approximation,which is used to solve the two-dimensional electromagnetic scattering problem.Numerical results are compared with those by the conventional method of moments (MOM) and analytical solutions.It is shown that the high-order MOM has higher computational precision with lower discretization.The new high-order basis function is applied to the scattering problems of electrically large conductors and other shaped objects.Numerical results prove that the proposed method possesses high accuracy and can reduce computational complexity efficiently. |
| Keywords: | best uniform approximation high-order basis function method of moments (MOM) scattering of electrically large conductive target |
