Abstract
The relationship between the tensors e and 8 is not obvious, and in Casimir [1] an experimental method is proposed to discover its possible breakdown. As a demonstration of this connection, either the conservation of energy [2] or the Onsager theorem [4] is used. However, the law of conservation of energy is fulfilled only in transparent media, and the Onsager theorem is based on the principle of microscopic reversibility and is demonstrated within the scope of phenomenological theory. In [5] Gyarmati proposed the possibility of the existence of a purely phenomenological means of proof. The work of Maksimenko and Serdyukov [6] is dedicated to an investigation of this route by requiring invariance of the scattering amplitude of electromagnetic waves by macroscopic particles relative to inversion of time. The principle of macroscopic reversibility is also used to determine the connection between the amplitudes of incident, reflected, and refracted waves (the Stokes relation) at the interface between a vacuum and an isotropie medium [7]. In the present work the Stokes relation is generalized to the case of the interface between an absorptive optically active isotropic medium and is used as evidence of the connection between the magnitudes of 7 and 6 in the absence of an internal magnetic field. Let right or left circularly polarized electromagnetic radiation impinge normally from a vacuum onto a semiinfinite optically active medium or cubic crystal Eo• = Eoe•
