“…During the last decades many numerical methods for solving Maxwell equations have been developed. Several of them are widely used: the finite-element method (FEM) (Monk, 1992;Zschiedrich et al, 2006;Monk, 2003), the finitedifference time-domain method (FDTD) (Yee, 1966;Prather and Shi, 1999;Taflove and Hagness, 2005) and the integral equation methods (IEM), which include the boundary element method (BEM) (Prather et al, 1997;Li, 2010) and the volume integral method (VIM) (Zwamborn and van den Berg, 1991;Botha, 2006;Chang et al, 2006;Shcherbakov and Tishchenko, 2010;van Beurden, 2011).…”
