Modified transfer matrix method for conducting interfaces

In this paper, the transfer matrix method is modified for study of optical wave propagation in layered media with conducting interfaces. Both the TE and TM mode transfer matrices are derived and their properties are discussed. As examples, the reflection and transmission coefficients of a single conducting interface and the dispersion equation of a Krönig–Penney photonic crystal are obtained, all being in agreement with previous results. Also, the coupling coefficients of two slab waveguides with conducting interfaces are found for TE and TM polarizations.
