“…The lower region, where the anomalous light penetration into a metal at frequencies below the plasma one occurs, is typical for any magnetoplasma system in the Voigt configuration and is connected with the modification of the plasma frequency by the cyclotron resonance (see, e.g., Ref. [109]). Interestingly, this phenomenon is accompanied by the effect of negative refraction, which can be observed not only in metamaterials but also in any gyrotropic (magnetic or chiral) system [110][111][112][113].…”

The propagation of light in Weyl semimetal films is analyzed. The magnetic family of these materials is known by anomalous Hall effect, which, being enhanced by the large Berry curvature, allows one to create strong gyrotropic and nonreciprocity effects without external magnetic field. The existence of nonreciprocal waveguide electromagnetic modes in ferromagnetic Weyl semimetal films in the Voigt configuration is predicted. Thanks to the strong dielectric response caused by the gapless Weyl spectrum and the large Berry curvature, ferromagnetic Weyl semimetals combine the best waveguide properties of magnetic dielectrics or semiconductors with strong anomalous Hall effect in ferromagnets. The magnitude of the nonreciprocity depends both on the internal Weyl semimetal properties, the separation of Weyl nodes, and the external factor, the optical contrast between the media surrounding the film. By tuning the Fermi level in Weyl semimetals, one can vary the operation frequencies of the waveguide modes in THz and mid-IR ranges. Our findings pave the way to the design of compact, tunable, and effective nonreciprocal optical elements. arXiv:1808.00342v3 [cond-mat.mes-hall]

Abstract-Single-crystalline silver filaments with periodic pearlchain-like structures are fabricated by electrodeposition without using any templates, surfactants, and additives. Simulations demonstrate that excited surface waves may sustain on silver pearl chains in middle infrared (Mid-IR) range. The propagation features of surface waves on the silver filaments indicate the structure application for Mid-IR wave transmittance.

“…Their applications have spread widely to various technological fields, which in return lead to revealing several novel properties of anisotropy medium, for instance, gyrotropic slab realizing tunable wave splitter [1], the realization of subdiffraction imaging using magnetic plasma [2], scattering free plasmonic optics with anisotropic metamaterials [3], manipulating negativerefractive behavior with a magnetic field [4] and so on.…”
