Abstract :
A vectorial modal method is developed for obtaining the modal spectrum of arbitrary guiding structures, and it is applied to the analysis of a one-dimensional periodic dielectric media with any number of lossy dielectric slabs within the unit cell. This formulation allows the study of electromagnetic scattering from multilayered periodic structures by means of the generalized scattering matrix theory. A study is performed of a wide variety of configurations with little computational cost. We have tested it by comparison with theoretical and experimental results found in the technical literature, and good concordance is shown.
