“…Therefore, it is interesting to address the applications of plasma in the field of SPPs because plasmas can enable us to realize tunable SPPs. There have been many studies in understanding SPPs involved with plasmas [26][27][28][29][30]. For instance, Lazar et al have investigated self-excited SPPs at the interface of counterstreaming plasmas [26].…”

The properties of surface plasmon polaritons (SPPs) excited in the plasma-dielectric-magnetic plasma structure are investigated theoretically. Both the normal and the absorbing dispersion relations of SPPs are derived and presented for transverse-magnetic polarization. The influences of the external magnetic field, collision frequency of plasma, background material dielectric constant, and thickness on the characteristics of SPPs are explored and discussed. Results show that these factors greatly alter the properties of SPPs. The results imply that the locations and propagation length of SPPs can be tuned. In addition, the results also show that a one-way dispersion relation of SPPs can be realized in the low-frequency regions when the external magnetic field is introduced.

The properties of surface magnetoplasmon polaritons (SMPPs) in a symmetric structure, composed of two semi-infinite regions of high-density two-dimensional electron gas (2DEG) separated by a thin film in Voigt configuration, are investigated. The normal and absorption dispersion relations for the transverse magnetic polarization are derived by correlating Maxwell's equation and the boundary conditions. It is demonstrated that the features of SMPPs are greatly influenced by the external magnetic field, collision frequency of 2DEG, the dielectric constant, and the thickness of the thin film, suggesting that the locations and propagation lengths of SMPPs can be governed accordingly. It is shown that the symmetry of the physical geometry preserves the symmetry of the dispersion relations of SMPPs. Furthermore, it is discovered that as the external magnetic field increases, the penetration depth of SMPPs decreases, while their energy loss reduces, implying that plasmons can propagate for longer distances. Additionally, it is observed that SMPPs in the symmetric configuration have a longer lifetime than those in the asymmetric configuration.

“…It has been addressed that the properties of graphene surface plasmons have been changed significantly due to QEs with unusual features which are completely different from those in the classical hydrodynamic model. The present work aims to study the dispersion characteristics of SMPPs in graphene sandwiched between two semi-infinite dielectrics under the perpendicular configuration by using the linearized quantum magnetohydrodynamic model [43][44][45][46]. The QEs, including quantum statistical and diffraction effects, are taken into account.…”

We investigate the properties of surface magnetoplasmon polaritons (SMPPs) in a graphene-plasmonic structure which is constructed as a graphene film sandwiched with two semi-infinite dielectrics under a perpendicular configuration. By solving Maxwell equations and quantum magneto-hydrodynamic equations with considering the quantum statistical and quantum diffraction effects, we deduce the dispersion relation of graphene SMPPs (GSMPPs) in detail. We show how the graphene electron density, the external magnetic field, and the dielectric constant, affect the features of the dispersion of GSMPPs in both classical and quantum cases. We find that the quantum effects (QEs) significantly alter the properties of GSMPPs, which are entirely different from those in a classical model. We find that the propagation speed of classical GSMPPs has small increases while the propagation speed of quantum GSMPPs has fast and sharp increases along with the increases in graphene electron density. We further find that the propagation speed decreases gradually by increasing the applied magnetic field in both classical and quantum GSMPPs. Moreover, we also find that the propagation speed of classical GSMPPs has fast decreases tending to zero at large wavenumber while the propagation speed of quantum GSMPPs has slow decreases tending to infinity with increasing the dielectric constant. Our findings elucidate that QEs play a crucial role in the properties of GSMPPs and their response to different parameters.
