| Event Description: Angelo Mascarenhas, National Renewable Energy Laboratory (NREL) Golden, Colorado Consequences of Spatial Antisymmetry on Light Light propagation in two and three dimensional lattices for which the index of refraction exhibits spatial antisymmetry is investigated in the ray and photonic crystal regimes. In these regimes, all the two dimensional antisymmetry groups for which light fails to propagate are identified, and the reasons underlying this failure analyzed using the topological approach for modeling flow in dynamical billiards. In the photonic crystal regime, the inherent absence of any pass bands for these groups indicates that Bloch’s theorem fails to apply to such antisymmetric periodic lattices. |
