Aerospace Propulsion Researcher

Microwave Rocket Gyrotron Technology Computational Plasma Physics

About

I am a Ph.D. student in the Department of Aeronautics and Astronautics at The University of Tokyo. My research focuses on Microwave Rocket Propulsion, Gyrotron Beam Systems, and Plasma Dynamics under high-power millimeter-wave irradiation. I am particularly interested in ionization wave propagation, shockwave formation, and energy conversion mechanisms through computational electromagnetics and fluid simulations.
