The Dynamics and Ducting Properties of Small-Scale Magnetoplasma Irregularities: Laboratory Modeling and Numerical Simulation

Small-scale plasma density irregularities, which develop under HF heating of the ionosphere, possess unusual dynamic properties, and can play the role of specific ducting structures for low-frequency waves. A numerical two-dimensional FDTD model has been created that allows one to investigate the interaction of VLF waves with systems of small-scale plasma irregularities, periodic and randomized. Laboratory experiments that simulate the dynamics of systems of small-scale magnetoplasma irregularities and their influence on the propagation of low-frequency waves are performed on a large-scale KROT device.
