Numerical Simulation of Ion Waves in Dusty Plasmas
… and electromagnetic waves and instabilities in dusty plasmas. Dusty plasmas are characterized by the presence of micrometer or submicrometer size dust grains immersed in a partially or fully ionized plasma. In this study, a two-dimensional numerical model is presented to study waves and …

Analysis of Plasma Wave Irregularities Generated during Active Experiments in Near-Earth Space Environment
… experiments: the injection of an artificial dust layer, and high-power radio waves. The objective of the "first experiment is to examine the effects of artificially created dust layers on the scatter of radars from plasma irregularities embedded in dusty plasma in space. This is an alternate …

A study of dusty plasma environment
… vehicles. One of such environment is the dusty plasma environment, where fine particles can be found in abundance. Dust particles interact with space plasma, get charged and are susceptible to the governing forces, hence are an important hazard to the space mission. This presents a …

Charging of aggregate grains in astrophysical environments.
… gas in which a portion of particles are ionized. Dust is a ubiquitous component of the universe, and when present in plasma, can form dusty plasma system. Dust in the plasma is generally charged due to the constant collisions with free moving electrons and ions. Cosmic dust can also be charged by …

Electron Temperature Enhancement Effects on Plasma Irregularities Associated with Charged Dust in the Earth's Mesosphere
… shows promise as a diagnostic for the associated dust layer. To investigate the temporal behavior of plasma irregularities thought to produce PMSE, this work describes a new model that incorporates both finite diffusion time effects as well as dust charging. The hybrid model utilizes fluid ions …

New-Measurement Techniques to Diagnose Charged Dust and Plasma Layers in the Near-Earth Space Environment Using Ground-Based Ionospheric Heating Facilities
… />source region associated with mesospheric dusty space plasmas may be modulated by radio wave heating with ground-based ionospheric heating facilities. These experiments show great promise as a diagnostic for the associated dusty plasma in the Near-Earth Space Environment which is believed …
