STRESS TENSOR FOR TURBULENT-PLASMA IN A HIGH-FREQUENCY ELECTROMAGNETIC-FIELD

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.
