The Maxwell Garnett theory does predict the effective permittivity of the structures investigated over the entire range of volume fractions of the two composites. The results show that the microwire spacing for the both composites have low influence on the complex permeability, while they exhibit significant effect on the real part of permittivity.

: Comparison between the effective permeability predicted with Maxwell Garnett, and numerical FEM results for cubic, tetragonal and orthorhombic arrays of spheres. : Effective permeability of an array made of particles with a rectangular size dispersion. We observe a large negative band of width Δν.

Based on the summary of MaxwellGarnett mixing rule (MG formula), the asymptotic forms for the frequency dependent term in MG formula is derived. Then the transition of periodic dielectric to periodic metal objects is studied. Numerical results are presented to verify the transition. A multieffective layer model is also evaluated.

The microwave permittivity (ɛ r) and permeability (µ r) of composite materials are tailored by adding various loading agents to a host plastic and are subsequently modeled using the Maxwell Garnett theory and second order polynomials.

Notations: LWB—linear Wiener bound; CWB—circular Wiener bound; MG1—Maxwell Garnett mixing formula in which ϵ h = ϵ 1, ϵ i = ϵ 2 and f = f 2; MG2—same but for ϵ h = ϵ 2, ϵ i = ϵ 1 and f = f 1; BG—symmetric Bruggeman mixing formula; A, B, C, D, E mark the points on the CWB, LWB, MG1, MG2, BG curves for which f 1 = and f 2 =

The Maxwell Garnett formula is explicitly given by [27] Another mixture formula was derived by Lord Rayleigh and is given by Rayleigh, Runge, Meredith and Tobias, McPhedran and McKenzie, McKenzie et al.

The effective magnetic permeability mu and effective dielectric constant epsilon are two equally important quantities for the characterization of electromagnetic properties of composites. For granular ferromagnetic metals, however, the presence of permanent magnetic moments means that the MaxwellGarnett theory is inapplicable to the .
