Magnetoplasmons along the Interface of Gyrotropic Plasma Surface – Longitudinal Propagation

Abstract

An analysis of propagation of surface polaritons–plasmons along the interface of gyrotropic plasma has been conducted. It has been shown that new wave characteristics appear due to the Rayleigh kind of the wave. The influence of both the plasma and the bounding media has been considered. The role of the interface has been demonstrated. The existence of many new phenomena is proved: the end point of the dispersion in strongly magnetized plasma, singular waves, the nonzero field and Poynting’s vector of the intersection of the dispersion curve and the complex zone, etc.

Surface waves in magnetized quantum electron-positron plasmas

“…Moreover, the case Γ 1 = Γ 2 is treated there in an incorrect manner. When Γ 1 = Γ 2 , one has singular waves, which has different dispersion relation [29,30] as can be seen in the next section. Note that from Eq.…”

“…On the boundary curve of a complex zone where the two constants are complex conjugate, the equality of the real parts of Γ 1 (ω, k) and Γ 2 (ω, k) is satisfied. Existence of such complex zones in classical gyrotropic plasmas has been proved by Ivanov et al [29,30]. They showed that the points of the complex-zone boundary are neither degenerate waves nor ones with zero field components.…”

The spectrum of electromagnetic waves in a magnetized gaseous plasma layer. Part 1. Wave dispersion

“…These lines divide the (ω n , k n ) plane into regions in which the values of α 2 1,2 are different. Consequently, different types of waves can propagate (Kushwaha and Halevi 1987;Ivanov et al 1998): for α 2 1,2 < 0 a bulk wave, for α 2 1,2 > 0 a Rayleigh surface wave, for α 2 1 > 0, α 2 2 < 0 a Rayleigh pseudosurface wave, and for α 2 1 and α 2 2 complex (in the complex zone) a generalized Rayleigh surface wave. The configuration of the propagation regions depends only on the magnetization.…”

“…One is for a weakly magnetized plasma (N < 1) and the other is for a strongly magnetized plasma (N > 1) (see Fig. 1 of Ivanov et al 1998). …”

“…In a gyrotropic plasma, the modes change their EH and HE character along the dispersion curve (Bevs and Everhard 1962;Ivanov and Nikolaev 1998). Furthermore, at small wavenumbers k n , the waveguide modes can change their hybrid character many times.…”
