Variability of Quasilinear Diffusion Coefficients for Plasmaspheric Hiss [PDF]
, 2019 In the outer radiation belt, the acceleration and loss of high‐energy electrons is largely controlled by wave‐particle interactions. Quasilinear diffusion coefficients are an efficient way to capture the small‐scale physics of wave‐particle interactions ...

Simulation study on parametric dependence of whistler-mode hiss generation in the plasmasphere
Earth, Planets and Space, 2021 We conduct electromagnetic particle simulations to examine the applicability of nonlinear wave growth theory to the generation process of plasmaspheric hiss. We firstly vary the gradient of the background magnetic field from a realistic model to a rather
