2013-12-24 follow, like Maxwell Garnett or Bruggeman formulas for dielectric, are hard to come by. Thus, at least mac-roscopically, the authors intend to bring back the due balance among the conjugate worlds of dielectrics and magnetics by basing their derivation on a similar model adopted by Maxwell Garnett and Bruggeman [2,4].

2005-7-25 We give a rigorous and original derivation of the Maxwell-Garnett mixing rule in the dynamical regime for a composite dielectric random medium with small spherical inclusions. For certain configurations of scatterers, we show that contrarily to the common belief, the Maxwell-Garnett formula can remain very accurate at a high concentration of scatterers and incorporate multiple-scattering ...

Another inherent limitation of the Maxwell Garnett formula is a quasi-static approximation requiring a distance between inclusions to be much smaller than the operating wavelength [8]. That requirement is usually satisﬂed in the microwave spectrum region, if one considers polymer

The results are compared to the Maxwell Garnett’s and Bruggeman’s predictions, and it is shown that the Maxwell Garnett approximation is quite robust for isotropic composites, albeit we do not consider strong resonance effects that can render simple mixing formulas grossly inaccurate.

2018-10-29 Maxwell's four differential equations describing electromagnetism are among the most famous equations in science. Feynman said that they provide four of the seven fundamental laws of classical physics. In this paper, we derive Maxwell's equations using a well-established approach for deriving time-dependent differential equations from static laws.
