Third-order implementation and convergence of the strong-property-fluctuation theory in electromagnetic homogenization.
The strong-property-fluctuation theory (SPFT) has been widely applied under the second-order approximation (also known as the bilocal approximation) to estimate the constitutive properties of effectively homogeneous composite mediums. A third-order mass operator approximation is developed here. The convergence of the long-wavelength, bilocally-approximated SPFT is demonstrated for isotropic chiral composite mediums, as well as for chiroferrite composite mediums.
