Frequency selective structures (FSS) in the form of two-dimensional gratings with non-resonant elements are investigated. It is shown that selective properties of these band reflective FSSs are realized at the rejection frequency when the inductive and capacitive terms in the transmission coefficient are cancelled mutually. Expressions for the reflection and transmission coefficients for the gratings consisting of thin metal rectangles are obtained. Also a set of similar FSSs with inductive and capacitive coupling elements is considered. The results of calculations are compared with experimental data.
