Fig. 13From: Simulation study on parametric dependence of whistler-mode hiss generation in the plasmaspherea Wave amplitudes of forward-propagating waves (\(t=0\sim 2.04\times 10^4[\Omega _{e0}^{-1}]\)); b instantaneous frequencies, and c corresponding absolute S values in different cases of the hot electron density. Data with wave amplitudes less than \(2\times 10^{-5}\) are eliminated. The green dashed line in c represents unityBack to article page
