“…One can obtain the value of ᾱD by using equations ( 12) and ( 13) for SPP parameters. The properties of cnoidal waves and solitons at the interface of dielectric and metal media are similar to the properties of nonlinear waves in the infinite medium [29] and optical fibers [4,[32][33][34][35][36]. One can describe, in particular, the topological insulators, Weil semimetal or Dirac metal by the nonlinear response of dielectric and conducting media [12,13].…”

The control of flow of surface plasmon polaritons (SPPs) propagating at the single interface of metal and dielectric media and also in plasmonic waveguides is considered. The SPP energy flux is sufficient for appearance of the nonlinear polarization of the media. SPP flow propagates along the interface as a quasiharmonic wave in the linear regime at weak intensity and as a cnoidal wave in the form of a pulse train or solitons in the nonlinear regime at strong intensity of the flow. The forms and periods of these waves are determined by the power of external source and the boundary conditions of the SPP flow excitation. The propagation of SPP flow in plasmonic waveguides depends on the phase shift under the effect of external electric field in the waveguide insert. Thereby, the energy flux of SPPs in the plasmonic waveguide can be controlled by the power of source and the external electric field also.

“…The nonlinear polariton wave in the waveguide with ε 1 > 0, χ 3 > 0 is E = C J (ω c −1 √ ε 1 r ) exp(i ϕ)cn(Cρ z − K 1 ( k), k). The polaritons propagate in the waveguide in the form of bunches with soliton envelopes, or in the form of the quasi-harmonic wave cn(Cρz − K 1 ( k), k) → cos(Cρz − π/2) at k → 0, which depends on the relation of parameters of the field and waveguide [30]. Another solution of the nonlinear equation for Z can be found in the form Z = −i √ 2/ρ(C − z), where C is the constant.…”

Some models of electromagnetic field interactions with linear and nonlinear dielectric media based on the approach of polarization and electromagnetic wave propagation in media are considered. It is shown that quasi-particles generated in the dielectric medium, called polaritons, have mass whose quantity depends on the efficiency of the electromagnetic field and interaction with the medium. The mass and velocity of polaritons can be controlled by the external electric field. The value of the mass of polaritons was measured in a transparent crystal.

“…It was caused by investigations of the electromagnetic wave generation, propagation, transformation, and their instability in the active and passive media [14][15][16][17]. The external magnetostatic field superposed to the bigyrotropic medium changes both the permittivity and permeability that influences the polariton spectrum and polariton wave velocity.…”

The ion and electron polarizations under the influence of high-frequency electromagnetic field and external magnetostatic field in a bigyrotropic medium (dielectric with magnetic subsystem) are considered. The polariton spectra in the bigyrotropic medium are received. It is shown that the polariton spectrum and the velocity of polariton wave can be controlled by the variation of the intensity and direction of external magnetostatic field. It becomes possible because the ion and electron Larmor's frequencies depend on the external magnetostatic field that leads to the appearance of several additional resonances of the permittivity and permeability of the medium. The wave vector and velocity of polariton wave that are close to the resonance frequencies vary depending on the wave frequency: the polariton wave velocity drops to zero before the resonance and increases after it. The wave velocity control may be used for designing controllable devices for a data-transmitting line.
