@article{Treumann2017PoyntingsTI, title={Poynting's theorem in magnetic turbulence}, author={Rudolf A. Treumann and Wolfgang Baumjohann}, journal={arXiv: Space Physics}, year={2017} }

Poynting's theorem is used to obtain an expression for the turbulent power-spectral density as function of frequency and wavenumber in low-frequency magnetic turbulence. No reference is made to Elsasser variables as is usually done in magnetohydrodynamic turbulence mixing mechanical and electromagnetic turbulence. We rather stay with an implicit form of the mechanical part of turbulence as suggested by electromagnetic theory in arbitrary media. All of mechanics and flows is included into a…

The first measurements of the electric field fluctuation spectrum over the inertial and dissipative wave number ranges in a Beta > or approximately = 1 plasma are presented, and the wave phase speed in this regime is shown to be consistent with the Alfvén speed.

Kolmogoroff's theory of locally isotropic turbulence
