Spatially periodic slots in metal plate make plate appear transparent at frequency of resonance of slots. Appears mostly reflective at high frequencies. Orthogonal slots accommodate circular polarization; one of two orthogonal slots in each pair eliminated if only one known linear polarization needed. Spectral response of plate tailored by choice of dimensions of slots.
