“…Later, Rosenberg et al (1999) considered a lower hybrid (LH) instability driven by a beam of negatively charged dust streaming across B, finding that this instability could be relevant for explaining the enhanced radar backscatter from space shuttle exhaust. Rosenberg and Sorasio (2006) have considered the possibility of LH instability in dust-gas formations from rocket exhausts injecting combustion products into the ionosphere (see Platov 2004). …”

Dusty plasma effects in near earth space and interplanetary mediumSpace Science Reviews, 2011, Vol. 161, Issue 1-4: 1-47 10.1007/s11214-011-9762-3Access to the published version may require subscription. Published with permission from:Springer Science+Business Media B.V.Space Science Reviews manuscript No. (will be inserted by the editor) Dusty plasma effects in near Earth space and interplanetary mediumReceived: date / Accepted: date Abstract We review dust and meteoroid fluxes and their dusty plasma effects in the interplanetary medium near Earth orbit and in the Earth's ionosphere. Aside from in-situ measurements from sounding rockets and spacecraft, experimental data cover radar and optical observations of meteors. Dust plasma interactions in the interplanetary medium are observed by the detection of charged dust particles, by the detection of dust that is accelerated in the solar wind and by the detection of ions and neutrals that are released from the dust. These interactions are not well understood and lack quantitative description. There is still a huge discrepancy in the estimates of meteoroid mass deposition into the atmosphere. The radar meteor observations are of particular interest for determining this number. Dust measurements from spacecraft require a better understanding of the dust impact ionization process, as well as of the dust charging processes. The latter are also important for further studying nano dust trajectories in the solar wind. Moreover understanding of the complex dependencies that cause the variation of nano dust fluxes is still a challenge.

The effect of charged dust particle on the electrical conductivity of weakly ionized dusty plasma is investigated. It is shown that the additional collision provided by charged dust particles can significantly alter the electrical conductivity of electron-ion plasma. The numerical results indicated that these effects are mainly determined by dust radius, density as well as the charge numbers on dust surface. The obtained results will support an enhanced understanding of the electromagnetic wave propagation processes in dusty plasma.

“…The parameters chosen in the simulation are as follows: B ∼ 5 × 10 −5 T, n e ∼ 0.994 × 10 5 cm −3 , n i ∼ 1.0 × 10 5 cm −3 , n d ∼ 0.006n i , T e ∼ 0.2 eV, T d = T i ∼ 0.1 eV, Z d ∼ 50 and m d ∼ 4 × 10 9 m p , where m p is the proton mass (Mendis & Rosenberg 1994). The dust particles are injected into the background plasma with a speed u d0 ∼ 2 km s −1 (Huba et al 2000;Rosenberg & Sorasio 2006). Then we obtain ω pe = 1.50 × 10 7 rad s −1 , ω pi = 0.93 × 10 5 rad s −1 , ω pd = 25.50 rad s −1 , Ω ce = 8.79 × 10 6 rad s −1 , Ω ci = 0.24 × 10 3 rad s −1 and Ω cd = 5.99 × 10 −5 rad s −1 .…”

“…The interaction between rocket exhausts and the background plasma has received growing interest owing to the potential role in the ionosphere (Fried & Conte 1963;Seiler, Yamada & Ikezi 1976;Shukla 1992;Mendis & Rosenberg 1994;Rosenberg & Krall 1994;Bernhardt et al 1995;Bharuthram & Singh 1997;Bharuthram & Rosenberg 1998;Rosenberg, Salimullah & Bharuthram 1999;Huba, Joyce & Fedder 2000;Scales & Ganguli 2004;Rosenberg & Sorasio 2006;Rosenberg, Bernhardt & Clark 2011;Bernhardt et al 2012;Chen 2016;Liu et al 2021).

“…It was found that instabilities may occur on the dust time scale. Subsequently, Rosenberg & Sorasio (2006) have investigated the lower hybrid instability driven by charged dust particles streaming across the geomagnetic field in the upper atmosphere and taken into account the effects of charged particles collisions with the background atmospheric molecules. It was found that the presence of unstable waves may create plasma density oscillations that could reflect radar signals.…”

Generation of the fluctuations by a charged dust beam in the ionosphere

et al. 2022

View full text Add to dashboard Cite

Different kinds of waves and instabilities in the F-region of the ionosphere excited by the relative streaming of the dust beam to the background plasma are studied in the present paper. The dispersion relations of different waves are obtained on different time scales. It is found from our numerical results that there are both a stable upper hybrid wave on the electron vibration time scale and a stable dust ion cyclotron wave on the ion vibration time scale. However, the chaotic behaviour appears on the dust particles vibration time scale due to the relative streaming of the dust particles to the background plasma. Such instabilities may drive plasma irregularities that could affect radar backscatter from the clouds.
