There are a number of pressing problems mankind is facing today that could, at least in part,
be resolved by space systems. These include capabilities for fast and far-reaching …

Plasma-surface interactions caused by electric propulsion devices are an important
spacecraft aspect of the design that is difficult to measure in ground-based facilities. The …

A novel Immersed-Finite-Element Particle-in-Cell (IFE-PIC) simulation tool is presented in
this paper for plasma surface interaction where charged plasma particles are represented by …

A magnetic focusing type Hall thruster was designed with a cylindrical magnetic seperatrix.
