Applied to 2D planar multilayer geometries, the method of moments (MoM) transforms integral equations into matrix equations whose entries become double integrals over finite domains in the spatial domain MoM, and single integrals over infinite domain in the spectral domain MoM. To efficiently evaluate these integrals, three algorithms are considered to evaluate the MoM matrix entries. These are: the spatial domain MoM in conjunction with the closed form Green's function; the spectral domain MoM using the generalized pencil of functions (GPOF) algorithm; and the FFT algorithm. All the approaches demonstrate good accuracy; however, in terms of numerical efficiency, the GPOF-based algorithm in the spectral domain MoM performs the best.
