WebJul 21, 2010 · Bernstein waves with parallel phase velocity close to c are useful for electron acceleration. Such waves can be excited by nonlinear mixing of two nearly counter propagating intense electromagnetic waves across the magnetic field when the frequency difference in them is close to electron cyclotron frequency. WebApr 12, 2024 · The MS waves excited in such a condition are believed to satisfy the kinetic ion Bernstein wave dispersion relation which differs significantly from the CPDR (Liu et al., 2011; Min & Liu, 2015). However, how the kinetic effects in the wave dispersion relation may affect the electron scattering by MS waves has seldom been investigated. sunflower for my love lost ark https://daniutou.com
