Abstract

The reflectivity of photonic cluster is important property for nanophotonic applications especially when one needs to hide the cluster or to make it extremely visible. Currently, where are no methods clearly describing how to create the photonic cluster with the predefined reflectivity. In this paper several analytical methods are proposed to create the photonic cluster with minimal or maximal reflectivity. The proposed methods are applicable for the clusters made of small particles.
