Electrodynamic properties of two-dimensional Bragg resonators of planar geometry

Electrodynamic properties of two-dimensional (2-D) Bragg resonators of plan ar geometry realising 2-D distributed feedback are studied theoretically an d experimentally. It was shown that the resonators possess high selectivity over both longitudinal and transverse mode indexes and the eigenmodes spec trum is defined by the profile of the corrugated surface of the conductors forming the resonator. Results of the theoretical analysis agree well with the data obtained in "cold - microwave measurements of the frequency depend ence of the transmission, refection and transverse scattering coefficients.
