Diffraction of plane electromagnetic waves by a wedge with perfect mixed anisotropic conductivity sides in a chiral medium

“…On isotropic conducting boundaries, both mutually orthogonal tangential components of the electric or of the magnetic field strength vanish. They are supplemented with anisotropic boundaries possessing perfect mixed conductivity and capable not to change the polarization state of a circle-polarized wave on reflection [5]. In the English-language literature, the abbreviation SHS (Soft and Hard Surface) is used to designate surfaces of this type because they possess properties similar to those of perfectly soft or perfectly hard surfaces in acoustics if the plane of incidence of an electromagnetic wave is perpendicular or parallel to a direction selected on the surface.…”

Transformation of the vector part of the 4-momentum in the Dirac equation and in Maxwell’s equations in Majorana form for chiral media

“…In the case of electromagnetic radiation, an expression similar to (14) exists for a chiral medium [19]. In this case, the chirality coincides in value with 3 N .…”

“…relation(19) also holds, and from here, a relation for the wave function of the form (21) also follows. For nonrelativistic velocities, the last condition is equivalent to3 1/ 2 N N = ≈ .The relation of the form (21) is essential for both a "neutrino" ("antineutrino") and for an electron, as it does not contradict a qualitative understanding of the (22) proceeds in nuclei, and in this case, at high densities of matter, the necessary values for the "…”

Diffraction of plane Beltrami waves by a wedge with nonidentical sides showing mixed anisotropic conduction immersed in a chiral medium

“…Under certain conditions, goffered metal surfaces and periodic strip structures behave as artificial "soft" and "rigid" anisotropic boundaries with respect to an electromagnetic field [3]. At such a boundary, the tangential components of electric and magnetic field strengths vanish along a selected direction and, therefore, a wave reflected from the boundary retains the initial state of left or right circular polarization [4]. As applied to a chiral medium this implies that a unilateral anisotropically conducting surface of mixed type does not couple normal waves of the boundless medium.…”
