摘　　要：Recently, higher order methods for solv-ing scattering from complex object have received intensive attention. The advantage of using higher order methods lies in their ability to represent fields/currents and model geometries more accurately than conventional low-order methods. At the same time, these methods enable us to represent the current distribution on the surface of scat-terer with less number of unknowns. These methods in-clude higher order patches and higher order basis func-tions. In this paper, the curvilinear triangular patch com-bined with higher order interpolatory vector basis func-tions and FMM is used to realize fast, accurate solution of electromagnetic problems. It attains much less unknowns than traditional low-order basis functions, while not sacri-ficing any accuracy. Some representative results are given to demonstrate the validity of the proposed method.
