Reduced magnetofluid dynamics in the lowerhybrid frequency range
Abstract
The electromagnetic twofluid dynamics for plasmas in a strong applied magnetic field is investigated using a model for phenomena having frequencies in the range Ω_{i} ≪ ω ≪ Ω_{e} and long parallel wavelengths ɛ≡L_{⊥}/L_{∥} ≪ 1. The model retains the essential nonlinear physics of the magnetosonic, lowerhybrid, and oblique whistler waves. At least two unstable modes can exist for equilibria with magnetic shear; a local magnetic interchange whistler mode and a collisionless tearing mode. These modes are studied using a quadratic energy relation for linear stability and by threedimensional timedependent numerical computations.
