Morphology and diagnostic potential of the ionospheric Alfvén resonator
Autor: T. N. Polyushkina, Alexander Potapov, Battuulai Tsegmed
Publikováno v: Solar-Terrestrial Physics, Vol 7, Iss 3, Pp 36-52 (2021)
The layering of the ionosphere leads to the formation of resonators and waveguides of various kinds. One of the most well-known is the ionospheric Alfvén resonator (IAR) whose radiation can be observed both on Earth’s surface and in space in the f

Estimation of the Ionosphere Critical Frequency Without Radio Sounding
Autor: T. N. Polyushkina, Alexander Potapov
Publikováno v: IEEE Transactions on Geoscience and Remote Sensing. 58:5058-5065
The frequency parameters of the ionospheric Alfven resonator (IAR) emission show a close connection with the critical frequency foF2 of the ionospheric F2 layer. However, the quantitative characteristics of the connection are unstable and can vary si

Response of IAR frequency scale to solar and geomagnetic activity in solar cycle 24
Autor: Alexander Potapov, T. N. Polyushkina
Publikováno v: AIMS Geosciences, Vol 6, Iss 4, Pp 545-560 (2020)
The ionospheric Alfvén resonator (IAR) is an integral element of the entire ionosphere-magnetosphere system. It plays an essential role in energy exchange and interaction between the magnetosphere and ionosphere. The parameters of this resonator ref

Considering the potential of IAR emissions for ionospheric sounding
Autor: K.G. Ratovsky, Alexander Potapov, T. N. Polyushkina, A.A. Mylnikova, A.Yu. Pashinin, B. Tsegmed, A. V. Oinats, I. K. Edemskiy
Publikováno v: Journal of Atmospheric and Solar-Terrestrial Physics. 164:229-234
Knowledge of the ionospheric state allows us to adjust the forecasts of radio wave propagation, specify the environment models, and follow the changes of space weather. At present, probing of the ionosphere is produced by radio sounding with ground i

Narrow-band emission with 0.5 to 3.5 Hz varying frequency in the background of the main phase of the 17 March 2013 magnetic storm
Autor: Dmitry Baishev, T. N. Polyushkina, Alexander Potapov, Ravil Rakhmatulin, B. V. Dovbnya
Publikováno v: Solar-Terrestrial Physics, Vol 2, Iss 4, Pp 16-30 (2016)
We present results of the analysis of an unusually long narrow-band emission in the Pc1 range with increasing carrier frequency. The event was observed against the background of the main phase of a strong magnetic storm caused by arrival of a high-sp

Searching for an alternative method of the ionosphere monitoring
Autor: Alexander Potapov, T. N. Polyushkina, A. V. Oinats, B. Tsegmed, A.Yu. Pashinin, A.A. Mylnikova, I. K. Edemskiy, Konstantin Ratovsky
Publikováno v: 2017 Progress In Electromagnetics Research Symposium - Spring (PIERS).
The ionosphere monitoring is an important task because it allows us to adjust the forecasts of radio wave propagation, specify the environment models, and follow the changes of space weather. Currently sounding of the ionosphere is produced by the HF

Emissions of ionospheric Alfvén resonator and ionospheric conditions
Autor: Alexander Potapov, B. V. Dovbnya, R. A. Rakhmatulin, T. N. Polyushkina, B. Tsegmed
Publikováno v: Journal of Atmospheric and Solar-Terrestrial Physics. 119:91-101
We analyze continuous magnetic observations of ionospheric Alfven resonator (IAR) emissions at mid-latitude observatory Mondy. The measurements were by a LEMI-30 search-coil magnetometer covering the period from March 2010 to May 2011. The results ar

Experimental evidence for direct penetration of ULF waves from the solar wind and their possible effect on acceleration of radiation belt electrons
Autor: A. S. Potapov, T. N. Polyushkina
Publikováno v: Geomagnetism and Aeronomy. 50:950-957
The event of March 12–19, 2009, when a moderately high-speed solar wind stream flew around the Earth’s magnetosphere and carried millihertz ultralow-frequency (ULF) waves, has been analyzed. The stream caused a weak magnetic storm (Dst min = −2
