深亚波长人工带隙的调控机理与新效应的研究

In this proposal, we will study the artificial micro structures with deep subwavelength scale，especisally focus on the formation mechanism and new phenomena of deep subwavelength artificial bandgap, as well as their effective applications of new devices and technology. Our project mainly includes these facets: we will study the deep subwavelength effects caused by the band gap formation mechanism of resonant coupling system and the related far-field exchange and near-field coupling hybrid mechanism. The mechanism of radiation near field interference, the effect on the induced special photon bound state and photon transport behavior in deep subwavelength materials will be studied. We will discuss the influence of the effects of electromagnetic field reconfiguration and strong localization of deep subwavelength materials on the properties of atomic (or artificial atom) dynamics, quantum interference, electromagnetic induced transparency，photonic bandgap topological effect, photon-spin orbit coupling and so on. We will explore the possibilities of designing deep subwavelength microstructural elements and the coupling arrangement, and study the properties of coupling states between the elements in the periodic array and the regulation mechanism for the far-field direction synthesis characteristics. The research results of the project not only have important scientific significance, but also have extensive guiding significance to the application of related devices.
