A theory of incoherent scattering of radio waves by a plasma: 4. The effect of unequal ion and electron temperatures

摘要: The theory is extended to include the effects of unequal ion and electron temperatures a magnetic field. Two approximate formulas for total scattered power are derived, which, with certain restrictions, applicable (1) when Te/Ti ≲ 1, (2) » 1. For moderately large values temperature ratio, full numerical calculation necessary. In contrast equilibrium case, not independent field unity. interesting case in which cyclotron radius compared wavelengths interest, but small, mass ratio me/mi replaced by an effective (me/mi) sec2 α, where α angle between propagation vector k As approaches 90°, ceases be scattering significantly altered. general behavior has simple physical explanation. can considered from acoustic waves that particles contribute most their Landau damping.
