Abstract : The effects of an upper bound on the ionization frequency for a plasma slab irradiated with intense microwave power are investigated using a Chapmanfunction model. A quadrature algorithm is developed for the numerical computation of exact steadystate electron density profiles. The results for both stable and unstable profiles are analyzed in terms of a stability condition involving the deposition rate of microwave power. The dynamics of the electron distribution within the slab is treated approximately by constraining the density profiles to a sinusoidal form. A dynamical interpretation of stability then emerges from the approximate electron gainloss equation. The stability problem is also formulated graphically by the introduction of a potentiallike function. Steadystate characteristic curves for the plasma slab are calculated using sinusoidal density profiles; typical contours of constant net electron gain rate are similarly presented. (Author)
