Light-matter interactions in a material may be dramatically influenced 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 first 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 effects. The former can not be treated in case of local effective medium description.
