Non local effects in cone‑shaped metamaterials

Abstract

Light-matter interactions in a material may be dramatically infuenced by the features of the medium. Moreover, the electromagnetic characteristics of the material in the nearby areas may make a dramatic impact as well. Following the frst scenario, the medium is considered to be local, whereas in the other case, it is nonlocal. It has been demonstrated by the current works on light-matter interactions in composites that novel optical phenomena is enabled by nonlocal efects. The former can not be treated in case of local efective medium description.
