Lattice Resonances in Metasurfaces Composed of Silicon Nano-Cylinders
Department of Electrical and Computer Engineering
We investigate lattice resonances (LRs) in metasurfaces (MSs), composed of silicon nano-cylinders. It is revealed that LRs can be detected through concentration of fields at specific locations in the gaps between nano-cylinders. Formation of LRs appears to significantly modify the resonance responses of MSs, transforming elementary responses into collective phenomena. Their contribution in red-shifting of resonances at increasing the lattice constants and in phenomena, associated with Rayleigh anomalies, are discussed.
