Analysis of Electromagnetic Wave Reflection through Isotropic Parallel Plates

Abstract

This study focuses on the reflection of electromagnetic waves through isotropic parallel plates using the interferometric method, instead of treating the system as a whole and solving it with boundary conditions. This involves considering each of the multiple reflections that occur in these types of systems to obtain a development with different terms that converge to the exact solution. Thus, we aim to examine whether the initial reflections alone are sufficient for a good approximation. Expressions for the reflection coefficients for parallel (p) and perpendicular (s) polarizations were derived. The results demonstrate that relying solely on the first reflection is not a suitable approximation, whereas considering the first two terms proves to be accurate.
