A high frequency electromagnetic pump wave transmitted into the ionospheric plasma from
the ground can stimulate electromagnetic radiation with frequencies around that of the …

A review is given of the current state-of-the-art of experimental studies and the theoretical
understanding of nonlinear phenomena that occur in the ionospheric F-layer irradiated by …

We report on artificial descending plasma layers created in the ionosphere F region by high-
power high-frequency (HF) radio waves from High-frequency Active Auroral Research …

We present a short review of research using “Sura,” a multipurpose radio facility of the
Radiophysical Research Institute of Nizhny Novgorod, which is aimed at studying space, the …

Optical emissions and incoherent scatter radar data obtained during high-frequency
electromagnetic pumping of the ionospheric plasma from the ground give data on electron …

Powerful electromagnetic (EM) waves can exert well‐defined influence on the atmosphere,
ionosphere, and magnetosphere. These active EM interactions can provide spatiotemporal …

Experimental results of resonant high‐frequency (HF) scattering from small‐scale
geomagnetic field‐aligned plasma irregularities excited by electromagnetic HF pumping of …

The frequency of a high‐power HF radio wave incident on the ionosphere was swept, using
a computer‐controlled transmitter signal, in< 10 s within a 60‐kHz‐wide frequency band …

UHF electromagnetic emission (with a frequency near 600 MHz) from the F-region of the
ionosphere pumped by an HF powerful radio wave is revealed. Possible mechanisms of the …

Experimental evidence points toward magnetic‐field‐aligned small‐scale plasma density
striations as responsible for the long time features of stimulated electromagnetic emissions …
