Plasma physics, technologies, and space propulsion

Detail

Plasma is the fourth state of matter consisting of roughly equal numbers of positively and negatively charged particles in addition to neutral particles. The dynamics of the charged particles are significantly influenced or controlled by self-induced and applied electromagnetic fields; the plasma medium can induce various linear and nonlinear phenomena and leads technological innovations, e.g., the industrial plasma technologies and space propulsion devices. The team is working on the fundamental plasma physics and technologies of low-pressure discharges and applications to innovative space propulsion, via laboratory experiments and theories.
