Abstract :
In this paper the fast multipole method (FMM) combined with curvilinear triangular patch is used to realize a fast accurate solution of 3D vector scattering from the conductor with arbitrary shape. It attains less unknowns than the traditional RWG method and does not sacrifice any accuracy. If higher order basis functions such as interpolation vector basis is defined over the curvilinear triangular patch, the improvement effect will be better.
