✦ Synopsis
Poynting flux do not coincide. As a technique to treat such a situation by geometrical optics, electromagnetic energy fluxes of absolute value [ 1 J have been introduced and the circularly polarized absolute-value rays have been proposed [2].
To provide an example of circularly polarized a hlute-value rays in a nondispersive absorbing medium, the theory of ray tracing is presented in the case in which a plane wave is incident on a planar layered medium. Specific tracing methods are presented for the loci of the real phase plane normal, the loci of the projection ray related to the flow line of the normalized Poynting flux, the loci of the circularly polarized absolute-value rays, and the intensities of these rays. The relationships to Poynting flux and their tracing method are described. Further, in the planar layered medium, an anisotropic projection ray index of refraction is introduced to the projection ray. It is shown that Fermat's principle holds under this index of refraction. On the other hand, Fermat's principle also holds in the tracing of the trajectory of the real-phase plane normal. In Fermat's principle of the projection ray, its relationship to the energy flux density is new.
