摘要
In this letter, we apply a version of the fast multipole method (FMM) to reduce the storage and computational requirement of the boundary integral (BI) in the finite-element boundary-integral method, By virtue of its O(N-1.5) operation count, the application of the single-stage FMM results in substantial speedup of the boundary-integral portion of the code, independently of the shape of the boundary-integral contour, We discuss the efficiency of the method and present an application of the technique to electromagnetic scattering from large grooves recessed in a ground plane.
