Scattering of Electromagnetic Waves Incident Normally on Square Patch-Type FSS Placed at the Interface between Two Dielectric Media
In this paper an analytical approach for calculating scattering matrix elements for the case of normal incidence of the plane electromagnetic waves on the square patch-type Frequency Selective Surface (FSS), which is placed at the interface between two dielectric media is proposed. Analytical expressions for the reflection and transmission coefficients are shown to be accurate enough for practical purposes.
