Ionospheric heating by high-power high-frequency (HF) waves has been widely recognized as a powerful tool to modify the ionosphere (P. Bernhardt et al., 2010). Such modifications have practical applications in the radio-communications and the regulation of high energy electrons to protect spacecraft in geospace. On the other hand, interactions between the injected electromagnetic (EM) waves and the ionosphere can effectively turn the ionosphere into a plasma laboratory without walls, to explore fundamental physical processes of plasma in the near-Earth space environment. Therefore, since the 1970s, the heating experiments by ground-based powerful HF facilities sprang up all over the world, such as the Arecibo, EISCAT, SUDA and HAARP (Gordon & Carlson, 1974;Rietveld et al., 2000). Numerous scientific observations have been obtained with these facilities, along with theoretical explanations which have been commonly accepted (Rietveld et al., 2016;Streltsov et al., 2018).The parametric decay instability (PDI) is one of the most fundamental and predominant physical processes generated in the ionospheric heating experiment, which can convert the ground-transmitted incident pump wave into another high-frequency-wave mode (EM or electrostatic wave) and a low-frequency-wave mode (Fejer, 1979;Gurevich, 2007;Robinson, 1989;Wang et al., 2016). As consequences of energy and momentum conservation, these waves must allow frequency and wavenumber matching relations, that is, f H ± f L = f pump , k H ± k L = k pump , where the subscripts H, L, and pump refer to the high-frequency-wave mode, the simultaneous low-frequency-wave mode, and the incident pump wave, respectively. f is the

“…The possibility of the effects observed by SWARM was previously demonstrated in laboratory experiments. The laboratory modeling performed with KROT plasma facility under the experimental conditions similar to the conditions in the ionosphere, where the plasma irregularities develop under the impact of high‐power HF radio waves, has revealed redistribution of plasma accompanied by electric currents (Aidakina et al, , ; Kostrov et al, ; Starodubtsev et al, ). Because the heated electrons escape along the magnetic field lines, channels with reduced plasma density and enhanced N e above the depletion are formed.…”

A series of experiments were conducted with a conjunction between the midlatitude SURA ionospheric heating facility and the multisatellite SWARM mission. We present the first observations made by SWARM on the plasma perturbations and electric currents induced in the F2 region ionosphere by the high‐power high‐frequency O‐mode radio wave pumping. In the heated region, significant effects include a localized increase of the electron temperature accompanied by stratification of the electron density and the magnetic signatures of field‐aligned currents (FACs). The spatial structure and amplitude of FACs indicate that the current system is likely associated with the unipolar diffusion and excitation of eddy electric currents in the ionosphere. Similar effects are revealed in the laboratory experiment but not previously observed in space.

“…The features of interaction of electromagnetic fields with magnetic-field-aligned plasma density irregularities have been the subject of numerous studies, and there exists a vast literature on various aspects of radiation, propagation, and scattering of waves in the presence of such plasma structures in space and the laboratory [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. An especially strong interest in this problem has been motivated by resonant and guiding properties of a bounded cylindrical plasma in some frequency ranges.…”

Resonance interaction between the electromagnetic radiation from a dipole antenna and a cylindrical density depletion aligned with an external static magnetic field in a magnetoplasma is studied in the case where the antenna is located outside such a density irregularity. A distinctive feature of the presented analysis is using a realistic distribution of the antenna current instead of the assumed one. It is shown that such an antenna can excite plasmon resonances of the density depletion, along with the resonance at the plasma frequency of the outer region. In addition, previously unrevealed resonances of the total field, which are related to excitation of complex modes of the cylindrical density depletion, are discussed. The results obtained can be helpful in understanding the basic properties of resonance interaction of the antenna fields with cylindrical density irregularities in a magnetoplasma and planning the related experiments in the ionospheric and laboratory plasmas.
