✦ Synopsis

This paper presents a method for tracing the tlux line and Poynting flux amplitude in a geometrical optics field in relation to the circularly polarized absolute value ray when a plane wave is incident on a planar nondispersive layered lossy medium. For projected flux flow lines that are the projection of the Poynting flux flow lines onto the wavefront normal plane, it is shown that Fermat's principle holds for the projection flux flow lines if an anisotropic index of refraction of the projected flow lines related to the excitation method of the plane wave and dependent on the amplitude is introduced.
