“…For instance, in the case of the planar plasma boundary shape, most of the SWs are slow waves; they are either potential ones or at least can be considered in the potential approach (see, e.g., [2,3]), unlike the case of SW propagating along the plasma boundary with finite value of curvature radius [1].…”

Abstract-The properties of higher order radial modes of electromagnetic azimuthal surface-type waves (ASW) which propagate in partially plasma-filled cylindrical waveguides without external magnetic field are analyzed using analytical and numerical techniques. For a waveguide with plasma surrounded by dielectric material and encased in metal, the eigenfrequencies for higher order radial modes are obtained. It is found that the ASW higher radial modes propagate with shorter vacuum wavelength than the zeroth order radial modes and that the more favourable conditions for higher order radial mode propagation are for ASW's with larger azimuthal wavenumber in waveguides with wider dielectric layer and larger dielectric constant. A further salient feature of ASW higher radial modes is that a change in plasma waveguide parameters causes a drastic change in ASW eigenfrequency in contrast to the zero-th order modes which have a smoother frequency variation with effective wavenumber.

“…It should also be mentioned that since we have considered only the x ! 0 half space, left-right asymmetric oscillations [22][23][24] on the expansion fronts have been precluded.…”

“…Such surface oscillations, or surface plasma waves, are ubiquitous at the boundaries of plasmas, but they are evanescent in the surface-normal directions and usually weak. [22][23][24] However, Fig. 2 shows that in the expansion of a cold plasma slab, the oscillations of the normalized electron front can be of large amplitude and are stably modulated, and, depending of the initial ion and electron densities and the size of the edge ion layer, can be either in front of or behind the ion front (which in the present non-perturbative analysis actually also oscillates, but at very small amplitude and long wave length because of the large ion mass).…”

(2014) Expansion of a cold non-neutral plasma slab. Plasmas, 21(12) Expansion of the ion and electron fronts of a cold non-neutral plasma slab with a quasi-neutral core bounded by layers containing only ions is investigated analytically and exact solutions are obtained. It is found that on average, the plasma expansion time scales linearly with the initial inverse ion plasma frequency as well as the degree of charge imbalance, and no expansion occurs if the cold plasma slab is stationary and overall neutral. However, in both cases, there can exist prominent oscillations on the electron front. V C 2014 AIP Publishing LLC. Physics of

“…It is important to emphasize here that these resonant modes are not truly stationary eigen-mode states but rather are quasi-stationary states experiencing weak amplitude decay in time due to the energy outflow into the surrounding region. Such modes are called leaky modes [28]. As it was noted above, there are two types of resonances.…”

Abstract-Resonant modes of multi-layer structures which contain the regions of negative epsilon material (such as a metal in the visible range) are analyzed. Existence of two separate classes of resonant modes is demonstrated. One is related to the excitation of the surface mode at the interface of the regions with opposite signs of the dielectric constant and involve energy transport by evanescent modes throughout the whole structure. The second class involves propagating modes (which form the resonant standing wave) in some regions and the evanescent waves in other layers with ε < 0. It is shown that the resonant transmission is related to the existence of quasi-stationary leaky modes having a finite life-time and characterized by large wave amplitude in the trapping region. It is shown that both types of
