Finding the Incidence Angle for Rays Refracted Through Multiple Dielectric Layers

In this paper we propose a technique for finding the exact angle that a ray must be transmitted in order to arrive at a particular location after refracting through a dielectric medium. The technique is initially developed for a single dielectric medium but is shown to be applicable to multiple dielectric media with various widths and permittivities. Simulation results have shown that the proposed technique performs better than the existing techniques for low loss dielectrics and for certain incidence angles.
