WebEMTs of Maxwell-Garnett, Bruggeman and Looyenga models are employed to calculate the effective permittivity of the composite and results are compared for 2D and 3D models. Nanodielectrics with metal fillers exhibit percolative behavior, which enhances the dielectric constant of the composite by many times at the percolation threshold. WebWe attempt to describe the optical properties of such particles using Lorenz–Mie theory and a refractive index found from some effective medium theory (EMT) assuming the particle is homogeneous. We refer to this as the effective model. It is found that the deviations are minimal when utilizing the EMT based on the Bruggeman mixing rule. Web5 de ago. de 2024 · 2.1 The theory There are several methods for predicting the effective permittivity of the mixture material. The most famous method is the Maxwell–Garnett formula, which is based on the polarization induced by an external uniform field on isolated spherical inclusions placed in the host material. philips norelco cleaning cartridge alcohol
