# Bruggeman approach for isotropic chiral mixtures revisited

@article{Ross2005BruggemanAF, title={Bruggeman approach for isotropic chiral mixtures revisited}, author={Benjamin M. Ross and Akhlesh Lakhtakia}, journal={Microwave and Optical Technology Letters}, year={2005}, volume={44} }

Two interpretations of the Bruggeman approach for the homogenization of isotropic chiral mixtures are shown to lead to different results. Whereas the standard interpretation is shown to yield the average polarizability density approach, a recent interpretation turns out to deliver a null excess polarization approach. The difference between the two interpretations arises from differing treatments of the local field. © 2005 Wiley Periodicals, Inc. Microwave Opt Technol Lett 44: 524–527, 2005…
