### A Parallel Derivation to the Maxwell-Garnett Formula for ...

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].

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 two z-oriented surfaces have opposite charge and opposite normal, so they contribute equally. The x- and y-components are zero (since the integrand is antisymmetric and the ...

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.
