“…To further reduce the number of unknowns and simplify the calculation procedures, a simplified sub-entire domain (SSED) basis function method is proposed [8], in which the mutual coupling among the elements is neglected directly while computing the basis function so that it is shared by all the elements. In [9], the accuracy and efficiency of the ASED and SSED methods are compared and discussed. Furthermore, the fast multipole method (FMM) and conjugate-gradient fast Fourier transform (CG-FFT) are employed to further improve its efficiency [10], [11].…”
