Singular states of resonant nanophotonic lattices

Fundamental effects in nanophotonic resonance systems focused on singular states and their properties are presented.Strongly related to lattice geometry and material composition, there appear resonant bright channels and non-resonant dark channels in the spectra.The bright state corresponds to high reflectivity guided-mode resonance (GMR) whereas t
