| Abstract: | The partial flux expansion techniques are compared and evaluated among the nodal expansion method (NEM),the nodal Green's function method (NGFM),and the nodal Fourier expansion method (NFEM).The numerical results and analyses confirm that the accuracy of NFEM is higher than any finite-order NEM and is comparable with NGFM. |
