Derivation of extended Maxwell Garnett formula for carbon ...
A numerical effort for modelling the dielectric behaviour of the novel binary mixture of nematic liquid crystal and carbon nanotube (NLC:CNT) has been carried out using the Maxwell Garnett theory. The CNTs are treated as conductive anisotropic inclusions while the NLCs as dielectric isotropic or anisotropic matrix depending on temperature. Thus, the numerical expressions for the dielectric ...

Applicability of Effective Medium Approximations to ...
The best performing approach is the MaxwellGarnett approximation providing the accuracy on the order of 2% over the entire visible spectrum. The next one is the Bruggeman effective medium approximation with the average deviation of about 5% and the worst case of 15% deviation.

The Debye rigorous equivalent of the MaxwellGarnett ...
This paper responds to the recent needs for homogenized models of biphased mixtures, compatible with the FDTD electromagnetic simulation method. We propose an explicit transformation of the MaxwellGarnett mixing rule to the Debye relaxation formula. For that purpose, both models are rearranged into rational functions, and the conditions for their equivalence are derived.

Ferroelectrics such as barium titanate (BaTiO. 3), lead titanate (PbTiO. 3) and lead zirconium titanate (PZT) with the perovskite crystal structure have gained considerable interest in industrial sectors. Ferroelectric ceramics exhibit excellent dielectric properties but poor mechanical performances.

We have examined the MaxwellGarnett, inverted MaxwellGarnett, and Bruggeman rules for evaluation of the mean permittivity involving partially empty cells at particle surface in conjunction with the finitedifference timedomain (FDTD) computation. Sensitivity studies show that the inverted MaxwellGarnett rule is the most effective in reducing the staircasing effect.

The MaxwellGarnett mixing rule was initially used in a system where metal particles are encapsulated in an insulating matrix [12]. But in recent times the same mixing rule is applied for ceramic particle inclusions. This mixing rule is then modified and the effective
