Iterative Computational Scheme of Studying Electromagnetic Wave Propagation through Dielectric Thin Film Medium

Abstract

We present an approach to the computation of electromagnetic wave propagation through a dielectric thin film medium using iterative scheme. We used the Green's function technique involving some necessary boundary condition to solve the scalar wave equation. Non-vectorial aspects of the propagating wave through the thin film resulting from the film orientation were considered. The iterative numerical scheme based on the parallel use of Lippmann-Schwinger and Dyson's equations is demonstrated and used judiciously in the computation. The influence of the numerical parameters such as Green's function, thickness of the thin film, dielectric perturbation, ∆ε p (z) and mesh size, N p on the propagating wave for three region of electromagnetic wave were clearly assessed.
