UNIDIRECTIONAL WAVES IN ANISOTROPIC MEDIA AND THE RESOLUTION OF THETHERMODYNAMIC PARADOX

Abstract

This paper presents the resolution of so-called thermodynamic paradox, which was first pointed out by Lax and Button. It is shown that the Bresler's resolution is insufficient, and there can exist a single unidirectional mode in a lossless medium. The Poynting theorem is investigated for a discontinuity in the one-way system, and the solution is shown to exhibit a marked discontinuity depending on whether conductivity is zero or approaches zero. It is shown that Maxwell's equations with completely lossless medium which leads to thermodynamic paradox is in fact an ''Improperly-posed problem, '' which does not correspond to physical reality.
