Dusty plasmas with high electron depletion
Dusty plasmas with high electron depletion occur in a wide range of astrophysical and laboratory environments and constitute a strongly non-equilibrium plasma regime that is still not fully understood. In particular, the interaction of nanodust with the plasma, the resulting electron depletion, and …

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 …

Modeling of Plasma Irregularities Associated with Artificially Created Dusty Plasmas in the Near-Earth Space Environment
… scatter from plasma irregularities embedded in dusty plasmas in space. Plasma irregularities embedded in a artificial dusty plasma in space may shed light on understanding the mechanism for enhanced radar scatter in Noctilucent Clouds (NLCs) and Polar Mesospheric Summer Echoes (PMSEs) in the …

Computational studies of nonlinear dispersive plasma systems
… show up in weakly as well as strongly coupled plasmas, and play a significant role in the underlying plasma dynamics. Dispersive waves bring new challenges to the computer simulation of nonlinear phenomena. The goal of this thesis is to discuss two computational studies of plasma phenomena, one …

Characteristic measurements within a GEC rf Reference Cell.
… experiments performed within the complex (dusty) plasma community. The GEC cell, while providing for data comparison between systems due to its standardized design, does not exist without some variation between cells. In this work, two GEC rf Reference Cells located within the CASPER …

Large amplitude solitary waves in space plasmas
… electrostatic solitary waves in multispecies plasmas. In the following chapters we apply these general results to certain specific examples. In two-electron plasmas we consider electron-acoustic solitary waves in Chapter 3 and ion-acoustic solitons in Chapter 4. Then we consider dusty plasmas, …

Torsion heating in complex plasma crystals.
… to plasma, forming a newer field called complex/dusty plasmas. Complex plasmas host analogous structures to naturally occurring ones, like crystals, and may be studied to observe previously inaccessible features and effects in naturally occurring systems. Microparticles levitated in the plasma …

Plasma processes in pulsar environments
… are composed of multi-species electron-ion dusty plasmas. Conventional modelling of dust growth in this environment is based upon coagulation and nucleation of gas phase material. The second aim of this thesis is to study a possible spheroidal dust growth mechanism via plasma deposition. …

Plasma simulation with a dielectric object in the presence of an ion flow
Recent dusty plasma experiments have investigated the crystallization of dust grains near the edge of a plasma sheath. Some theories were proposed to explain the crystallization mechanisms. The purpose of this simulation work is to study the electrostatics of a dielectric object immersed in a …

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 …
