Response of Multilayer Materials to Electromagnetic Waves
The authors report on an analytical solution of the propagation,reflection and refraction of broadband electromagnetic signals within multilayer optical materials.The presented solution is processed in the Matlab program,which is suitable for a specifically oriented detailed analysis of a general problem.The paper includes a theoretical analysis and references to the generated algorithms.Comparison of the parameter changes is supported by graphical outputs of the algorithms.Algorithms created in the Matlab environment are verified by means of programs based on the finite element method,namely the ANSYS program.Inhomogeneities and regions with different parameters generally appear even in the cleanest materials.During the electromagnetic wave passage through a material there occurs an amplitude decrease and a wave phase shift; these phenomena are due to the material characteristics such as conductivity,permittivity,or permeability.Any incidence of a wave on an inhomogeneity results in a change in its propagation.The change manifests itself in two forms,namely in the reflection and refraction.In addition to this process,polarization and interference may appear in these waves.The methods described in this paper are well-suited for the analysis of beam refraction to the other side from the perpendicular line during the passage through the boundary.This phenomenon occurs in metamaterials.
