This Perspective paper deals with an overview of particle-in-cell/Monte Carlo collision
models applied to different plasma-propulsion configurations and scenarios, from …

In recent years, the increasing demand for simple and low-cost propulsion for small satellites
has given rise to a growing interest in low-power cathode-less plasma thrusters. Plasma is …

Plasma chemistry of main Earth atmospheric components in VLEOs is implemented in a
hybrid 2D axisymmetric simulation code to assess the air-breathing concept in an …

In this paper, we complete a full-thrust audit of an iodine-based gridded ion thruster. Prior
results have demonstrated excellent agreement between indirect and direct laboratory thrust …

The present work develops a full particle-based model that couples the particle-in-cell plus
Monte Carlo collision (PIC-MCC) simulation for plasma dynamics and the direct simulation …

A modular radio frequency plasma cathode has been designed to assess the sensitivity of
performance to several geometric parameters, operating conditions, and propellants. The …

Atmosphere-breathing electric propulsion (ABEP) is a type of electric propulsion system that
uses the atmosphere as a propellant source instead of a stored reservoir. This technology is …

Results in the development of a 150 W-class Hall thruster system employing iodine as
propellant are reported. Fundamental phenomena such as plasma chemistry and neutral …

For ion thrusters, the deflection of the ion beam caused by the relative translation of the grids
is one of the primary factors limiting the erosion lifetime of the ion optical system. A two …

Iodine is a promising propellant for future plasma thrusters used in space propulsion. It is
therefore important to understand the basic physics and chemistry of low-pressure iodine …
