On the effective permittivity of the multicomponent dielectric-dielectric nanocomposite structures.

In modern photonics, the calculation of effective optical properties of composite materials is of significant interest because it allows to predict the characteristics of the resulting material and provides a deeper understanding of the basic physical processes. There is no doubt that any research performed in this field is greatly Interesting as numerous aspects still remain enigmatic. The present article considers a multicomponent nanodispersed structure consisting of randomly oriented ellipsoidal nanoparticles in a matrix with a permittivity εm. Using the Maxwell-Garnett and Bruggeman models, the dependence of the effective dielectric permittivity of such a structure on the orientation of particles in an external field and the coefficient of volume filling of the medium with particles was studied.
