摘要: In this paper, an updated equivalence principle algorithm (EPA) is presented. Compared with previous work by the authors, high-order point sampling scheme used to reduce high-frequency noise in field projection. An tap basis introduced simplify formulation. With these schemes, can be solve multiscale problems substituting oversampled region a proper surface. Moreover, EPA also accelerated using attached unknown accelerations and multilevel fast multipole so that large solved efficiently.
