“…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]. SPP electric vector is the cnoidal wave with the time dependence and the damping along the transverse x-axis as the evanescent wave…”

“…Surface plasmon polaritons (SPPs) excited at the interface of metal and dielectric media in the linear and nonlinear regimes can be used for many applications [1][2][3][4][5][6]. One of the most important applications of plasmonics is the transmission of plasmon signals in processing chips [6], particularly by the short pulses [7] that leads to nonlinear plasmonic effects [2,4,6,[8][9][10][11][12][13][14]. The control of the SPP flow using external fields [2,[4][5][6][7] attracts special attention, particularly in metaldielectric [15] and graphene-dielectric [16,17] field effect transistors.…”

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.

This article discusses the importance of developing software and hardware complexes for data visualization and improving methods of presenting them in the modeling of low-temperature gas discharge plasma phenomena and related physical processes. In particular, issues related to creating a specialized distributed environment for solving gas discharge modeling tasks are considered. The use of computer graphics for visualization has allowed for a visual analysis of the obtained data and making necessary adjustments to the modeling process interactively with the data. The paper presents the results of visualizing a model of mercury-argon plasma in a coaxial microwave discharge. The application of local cross-sections of the computational domain for visualization has revealed the internal structure and peculiarities of the distribution of the electric field and electron concentration in the discharge tube. The obtained data served as the basis for creating an experimental prototype of a coaxial gas discharge optical radiation source.
