英文摘要： The project will study electromagnetic scattering suppression effects in optical sub-wavelength structures in theory and experiment. We will investigate the interactions between light and matter. Our aim are to find novel physics phenomena in the sub-wavelength structures constructed by different materials and arranged in different spatial periodicity; to find new physical mechanism and new rules in such physics phenomena. We will reveal the nature related on photonic topological insulator, the relations between scattering cloak and surface plasmon resonances. We will study on behaviors on Anderson localizations. We will study zero-refractive-index materials, in which we focus on scattering cloak and source transformer, etc. We will fabricate various kinds of high-dimensional sub-wavelength structures in optical region, and measure and analyze the behaviors related on scattering cloaking, zero-index, and topological transports. We will develop novel optoelectronic materials and technologies that are based on scattering suppression effects, so as to provide theoretical and experimental facts for high-dimensional optical sub-wavelength structure in the field of novel optoelectronic materials and novel optoelectronic devices.
