A plasma-wave discharge in a linear magnetic mirror configuration is proposed for laboratory modeling and studying of nonequilibrium magnetospheric processes producing electromagnetic radiation in a geomagnetic-field tube with an enhanced-density duct in the magnetosphere, as well as for demonstrating the ionization self-focusing and channeling of wave fields in the whistler frequency range. Nine demonstrations of nonlinear wave phenomena in the plasma of a laboratory model of an ionospheric-magnetospheric resonator with a density duct are discussed. A laboratory device is described that allows reproducing each of these demonstrations by setting appropriate experimental conditions.
