✦ Synopsis

don model, and therefore has nothing to do with finding out limits for the nonreciprocity parameter of bi-isotropic media. 3 Chirality is connected to geometrical properties of the microscopic matter and its parity breaking, whereas nonreciprocity emerges from connected electric and magnetic dipole moments inside matter and with the breaking of time-reversal symmetry. These two phenomena differ on such a fundamental level that the obscure transition from one to another, as w x was suggested in 1 , cannot hold. The possibilities for an observable nonreciprocity parameter in bi-isotropic materials w x 7 remain valid. 3 In fact, the low bounds for Љ in the Condon model are exceeded by w x many orders of magnitude in recent man-made chiral samples 6 . Therefore, also, the conclusion is dubious that the imaginary part of the chirality parameter and the phenomena associated with itᎏ like the circular dichroismᎏ would be insignificant effects.
