Three dimensional photonic structures specifically, woodpile photonic crystals, have great potential for manipulating light propagation such as localization and filtering. Efficient harvesting of the energy of the incident ...

Non-Hermitian potentials, as known since a decade, can favor unidirectionality of the flows in one and two-dimensional systems. Inspired by such counterintuitive property of non-Hermitian potential, we propose a novel ...
