Vp. Silin et Sa. Uryupin, STRESS TENSOR FOR TURBULENT-PLASMA IN A HIGH-FREQUENCY ELECTROMAGNETIC-FIELD, Plasma physics reports, 22(9), 1996, pp. 714-720
Consequences of the theory of ion acoustic turbulence are considered i
n order to find the force acting on an entirely ionized plasma in a hi
gh-frequency held. The electromagnetic stress tensor determined by the
electron plasma component is found. The anisotropy of electron scatte
ring by ion acoustic pulsations results in an angular structure of the
tensor that is different from the structure in the absence of turbule
nce: It is shown that due to both anomalously strong scattering of ele
ctrons by turbulent pulsations and the negligibly weak effect of turbu
lence on the inverse bremsstrahlung absorption of the radiation with a
frequency exceeding the Langmuir frequency, the absolute value of the
stress tensor is smaller than the corresponding value in the absence
of turbulence by a factor that is determined by the ratio of the effec
tive turbulent frequency and the electron-ion collision frequency. Bec
ause of this reduction in the absolute value of the electron stress te
nsor, the nonpotential components of the electromagnetic force increas
e by more than an order of magnitude.
