Before revision: Coupling constant and can be further related to the Tellegen ( refer to as reciprocity) and chirality parameter after substitute the above equations into the constitutive relations, gives Classification non-chiral chiral reciprocal simple isotropic medium Pasteur Medium non-reciprocal Tellegen Medium General bi-isotropic medium Examples Pasteur media can be made by mixing metal helices of one handedness into a resin.
