Abstract :
An augmented EFIE (A-EFIE) has been proposed to separate the contributions of the vector potential and the scalar potential for avoiding the imbalance at low frequencies. The corresponding low frequency fast multipole algorithm (LF-FMA) was also developed for solving the A-EFIE. Instead of the factorization of the scalar Green´s function by using scalar addition theorem in the LF-FMA, we adopt the vector addition theorem for the factorization of the dyadic Green´s function to realize memory savings. We are to develop a vector fast multipole algorithm for solving the A-EFIE.
