A preconditioned, multipole-accelerated, Krylov-subspace iterative algorithm\nfor the electromagnetic scattering analysis of three dimensional (3D),\narbitrary shaped dielectric structures composed of single and multi-layered\ndielectric materials is presented. A surface integral equation (SIE)\nformulation using Maxwells equations and the equivalence principle which\nproduces a well-conditioned matrix equation is applied. The surface integral\nequation is discretized using the well-known Method of Moments (MoM) based on a\nGalerkin scheme. The dense matrix is solved efficiently via an iterative method\naccelerated by the Multilevel Fast Multipole Method (MLFMM) coupled with an\nincomplete LU (ILU) preconditioning technique. Compared to the proposed methods\nin the literature, proposed method is much simpler and efficient to implement\nfor layered dielectric structures. 3D numerical examples are presented to\ndemonstrate the validity and accuracy of the proposed approach.\n
