Radio-Frequency Wave Simulation in Hot Magnetized Plasma - MFEM Workshop 2023

Explore a conference talk from the MFEM Workshop 2023 focusing on radio-frequency wave simulation in hot magnetized plasma. Delve into the challenges of modeling dielectric responses in high-temperature plasmas and learn about an innovative approach to constructing dielectric operators. Discover how Syun'ichi Shiraiwa and his team from Princeton Plasma Physics Laboratory propose an alternative method that incorporates all-order finite Larmor radius effects without explicitly containing higher order derivatives. Examine their use of rational approximation of the plasma dielectric tensor in wave number space and its application to modeling the 1D O-X-B mode-conversion of the electron Bernstein wave in non-relativistic Maxwellian plasma. Gain insights into the agreement between analytic calculations and wave energy conservation, as well as the connection between their construction method and superposition of Green's function for screened Poisson's equations. Explore potential extensions of this operator to multi-dimensional settings and understand its implications for advancing radio-frequency wave simulations in plasma physics research.
