Properties of slotted dielectric interfaces

A theoretical analysis of slotted dielectric interfaces based on an application of the Rayleigh-Ritz method is presented. Formulas for calculating the equivalent circuit parameters are derived for arbitrary polarization and angles of incidence. Numerical results are given which show that the slotted dielectric interface behaves essentially as a homogeneous anisotropic dielectric interface. Formulas and numerical values of the equivalent dielectric constants are also given.
