Dispersion Analysis of Metasurfaces With Hexagonal Lattices With Higher Symmetries

This article investigates the dispersion properties of metasurfaces with hexagonal lattices, including potential higher symmetric configurations. We explore the relationships between the periodicity of hexagonal lattices and their dispersion properties, paying special attention to how hexagonal peri...
