| Outline of Final Research Achievements |
Optical response of materials is undoubtedly essential for understanding their physicochemical properties. The conventional theoretical approaches to optical response of materials are usually based on the dipole approximation, which ignores spatial nonuniformity of a light and a selfconsistent light-matter interaction. However, such simplified approaches limit various optical phenomena. An optical near field (ONF) is a nonpropagating light localized at an interface region in nanostructures. The ONF-matter interaction is expected to cause unique optical phenomena. We have developed a generalized nano-optics theory and demonstrated unprecedented ONF excitation processes by resorting to the first-principles calculations.Furthermore, we have obtained fundamental scientific findings to design unified photonic-electronic functional materials.
