| Zusammenfassung |
| The stationary
self-focusing of whistler waves with frequencies near half of the
electron-cyclotron frequency in the ionospheric plasma is considered in
the framework of a two-dimensional generalized nonlinear Schrödinger
equation including fourth-order dispersion effects and nonlinearity
saturation. New types of soliton-like (with zero topological charge) and
vortex-like nonlinear waveguides are found, and their stability confirmed
both analytically and numerically. |
