Scaling of Spectral Anisotropy in Two-Dimensional Electron Magneto-Hydrodynamic Turbulence

Abstract

It is demonstrated using numerical simulation that spectral anisotropy in two-dimensional decaying electron magneto-hydrodynamic turbulence varies linearly with the ratio of fluctuating to mean magnetic field. Turbulent excitation scales larger (kλ _e<1) as well as smaller (kλ _e>1) than the electron skin depth scale length (λ _e) are shown to exhibit such linear scaling behavior.
