“…Therefore, the curve κ = 0 characterizing the isotropic medium crosses the TM z dispersion curve κ e = 0 of the uniaxial metamaterial. Note that such a curve crossing is mandatory by considering materials with allpositive permittivities, alike the pioneer paper by Dyakonov [10,13]. Our current case discloses some similarities with DSWs analyzed in Sec.…”

“…However, the first experimental observation of Dyakonov surface waves came into sight more than 20 years later, most specially caused by a weak coupling with external sources [11,12]. Indeed Dyakonov-like surface waves (DSWs) also emerge in the case that a biaxial crystal [13,14] or a structurally chiral material [15,16] takes the place of the uniaxial medium. The case of metal-dielectric (MD) multilayered media is specially convenient since small filling fractions of the metallic inclusions enable metamaterials with an enormous birefringence, thus enhancing density of DSWs and relaxing their prominent directivity [17][18][19].…”

Abstract:We analyzed surface-wave propagation that takes place at the boundary between a semi-infinite dielectric and a multilayered metamaterial, the latter with indefinite permittivity and cut normally to the layers. Known hyperbolization of the dispersion curve is discussed within distinct spectral regimes, including the role of the surrounding material. Hybridization of surface waves enable tighter confinement near the interface in comparison with pure-TM surface-plasmon polaritons. We demonstrate that the effective-medium approach deviates severely in practical implementations. By using the finite-element method, we predict the existence of long-range oblique surface waves.

“…At the same time, the literature is nearly silent about biaxial anisotropy. Sporadically, the optical properties of biaxially anisotropic interfaces are discussed [18][19][20][21][22][23][24]. However, a full discussion on ray-optics analysis of inhomogeneous bulk materials of biaxially anisotropic media cannot be found in the literature.…”

“…Hence, it is necessary to calculate the wave field at an anisotropic interface. Since we aim for a general approach of the theory we cannot ignore biaxially anisotropic interfaces, despite the fact that this subject is already known in the literature [18][19][20][21][22][23][24]. The optical properties of a uniaxially anisotropic interface are extensively discussed in [12].…”

Ray-optics analysis of inhomogeneous biaxially anisotropic media

Firm evidence of the biaxial nematic phase in liquid crystals, not induced by a magnetic or electric field, has been established only recently. The discovery of these biaxially anisotropic liquid crystals has opened up new areas of both fundamental and applied research. The advances in biaxial liquid-crystal-related topics call for a good overview on the propagation of waves through biaxially anisotropic media. Although the literature sporadically discusses biaxial interfaces, the propagation of waves through inhomogeneous biaxially anisotropic bulk materials has never been fully addressed. For this reason, we present a novel ray-tracing method for inhomogeneous biaxially anisotropic media. In the geometrical-optics approach, we clearly show how to assess the optical properties of inhomogeneous biaxially anisotropic media in three dimensions.

“…They can exist under certain conditions on an entirely free surface bounded by air, or at the interface separating two semiinfinite half-spaces. They propagate along the interface and decay in the transverse direction exponentially while having the field maximum on the interface [3][4][5][6][7][8]. They are useful for studying of the physical properties of the surfaces [9,10].…”

Abstract-A detailed study of surface TM modes at the interface between an isotropic medium and a uniaxial plasma is presented. Four cases for the isotropic medium, including normal, Left-handed, magnetic, and metallic media, are considered. The conditions for the existence of surface modes in each case are analyzed, showing that the existence is determined by the parameters of media, working frequency, and the direction of the principle axis. The Poynting vector along the propagating direction is also calculated. Depending on the media parameters and the frequency, the surface mode can have time-average Poynting vector in the opposite direction of the mode phase velocity.
