Influence of Electron and Ion Pressure Near the Lower Hybrid Resonance

Abstract
Near the lower hybrid resonance the power transfer from electromagnetic waves to a plasma cylinder is calculated with the inclusion of electron and ion pressures. Ion-electron collisions are accounted for in addition to the collisions of charged particles with neutrals. Drastic deviations from calculations neglecting the pressure effects occur for plasmas of low electron density and/or small radial extent. Different ranges of a specific ratio comparing the influence of collision with that of pressure terms are investigated.
