On the Effective Dielectric Permittivity of Nanocomposite Structures

Abstract

During the investigation of multicomponent nanodispersed structures using magnetic, optical, and magneto-optical methods, it was discovered that they don't follow the principles of classical physics. Undoubtedly, any experimental or theoretical research performed in this field is greatly Interesting as numerous aspects still remain enigmatic. The article considers a multicomponent nanodispersed structure consisting of randomly oriented ellipsoidal nanoparticles in a matrix with a permittivity ε_m. Formulas are obtained for calculating the effective dielectric permittivity of such a structure. It is shown that the calculation of the average value of the polarization of particles will be brought to the introduction of the effective value of the depolarization coefficient. The dependence of the effective dielectric permittivity of a single-component nanostructure on its structural parameters has been studied.
