Test Charge Response of a Dusty Plasma with size and charge distribution

More about the book

The thesis explores the electrostatic response of dusty plasma to a moving test charge, focusing on grain size distribution and charging dynamics. It reveals that dynamic charging enhances shielding effects, with a separate study illustrating a delayed potential response. The findings indicate spatial damping and phase shifts in potential due to grain charging. By integrating these aspects, the research presents generalized results that encompass previous studies on each effect individually, highlighting its significance in space and astrophysical plasmas.
