“…Notice that according to this expression, the anomalous refraction within the uniaxial approximation occurs for any angle of incidence. This absence of a critical angle in this slab made of natural occurring MO materials differs from the behavior of uniaxial bianisotropic (artificial) metamaterials with permittivityˆ = diag( xx , xx , zz ) and permeabilityμ = diag(µ xx , µ xx , µ zz ) [7].…”

“…In those regions, and as explained in the previous section, the uniaxial approximation predicts that incoming waves may be refracted into the slab as hyperbolic waves with k z given by the expression of Eq. (7). Now we turn to the analysis of the refraction of a plane wave impinging in our InSb slab.…”

“…This special feature of hyperbolic metamaterials makes it possible their application for negative refraction devices, subwavelenght imaging and superlensing, and hyperbolic waveguides [5,6]. In addition, they can exhibit anomalous refraction, which is the inversion of the transversal component of the Poynting vector once the electromagnetic wave enters into the medium [7]. In this work we explore the possibility to use a sim-ple semiconductor to mimic the behavior of a hyperbolic metamaterial in the far-infrared range of the electromagnetic spectrum.…”

“…With the assumption that the permittivity tensor is diagonal,ˆ = diag( xx , xx , zz ), it is easy to analyze the refraction of a plane wave by the slab [7]. Considering first the case of transversal electric (TE) polarized waves E = E 0ŷ e i(kxx+kzz−ωt) , the solution of Maxwell's equations lead to the following dispersion relation inside the slab first interface) is given by…”

Magnetic-field controlled anomalous refraction in doped semiconductors

We predict here that a slab made of a doped semiconductor can exhibit anomalous refraction under the application of a static magnetic field. This anomalous refraction takes place in the far-infrared range and it occurs for any angle of incidence. We show that this effect is due to the fact that a doped semiconductor under a magnetic field can behave, to some extent, as a hyperbolic metamaterial. We also show that the occurrence of this anomalous refraction enables a semiconductor slab under a magnetic field to partially focus the electromagnetic radiation. The remarkable thing in our case is that we deal with naturally occurring materials and the anomalous refraction can be tuned at will with an external field.

“…On the other hand many laser crystals and nanostructures (metamaterials, two-dimensional systems) are anisotropic [31]. The left-handed metamaterials are usually anisotropic and rather difficult to make isotropic one [32]. Last decade arise great interest to the anisotropic two-dimensional materials such as graphene with honeycomb hexagonal lattice, phosphorene with a puckered honeycomb configuration and strong in-plane optical anisotropy, hexagonal boron nitride (h − BN ), M oSe 2 , W Se 2 and others [6,33,34].…”

The system of equations of self-induced transparency (SIT) for extraordinary wave in uniaxial anisotropic media by means of generalized reduction perturbation method are transformed to the coupled nonlinear Schrödinger equations. It is shown that in the theory of SIT the second derivatives have significant role and leads to the formation of a vector 0π pulse oscillating with the sum and difference of the frequencies. An explicit analytical expressions for the profile and parameters of the nonlinear wave are obtained. It is shown that along with scalar 2π pulse, the vector 0π pulse is also the basic pulse of SIT and the scalar 0π pulse of SIT is only an approximation which can be considered in some special cases. The conditions of the existence of the nonlinear extraordinary wave depends on the direction of propagation. The profile of the vector 0π pulse in anisotropic crystal of ruby is presented with characteristic parameters which usually met in experiments.

Some physically interesting properties and effects of wave propagation in biaxially anisotropic left-handed materials are investigated in this paper. We show that in the biaxially gyrotropic lefthanded material, the left-right coupling of circularly polarized light arises due to the negative indices in permittivity and permeability tensors of gyrotropic media. It is well known that the geometric phases of photons inside a curved fiber in previous experiments often depend on the cone angles of solid angles subtended by a curve traced by the direction of wave vector of light, at the center of photon momentum space. Here, however, for the light propagating inside certain anisotropic left-handed media we will present a different geometric phase that is independent of the cone angles. The extra phases of electromagnetic wave resulting from the instantaneous helicity inversion at the interfaces between left-and right-handed (LRH) media is also studied in detail by using the Lewis-Riesenfeld invariant theory. Some interesting applications (e.g., controllable position-dependent frequency shift, detection of quantum-vacuum geometric phases and helicity reversals at the LRH interfaces etc.) of above effects and phenomena in left-handed media is briefly discussed.
