The effects of ambipolar static electric field on the electrostatic ton cyclotronwaves in a sheet plasma of thickness of the order of the ton Larmor radius pshave been studied ntunerically. The method is based on an integral equation inthe waventunber space derived from the Vlasov-Poisson system of equationsand on the direct computation of the integral equation. The effect of ambipolarfield for eigenfrequencies and eigenfunctions is studied systematically by varyingthe plasma thickness and the electron-to-ion temperature ratio. A strong negativeambipolar field seems to be effective for the penetration of r.f. field in sheetplasmas. The basic features for the case of the ideal sheet plasma, where theplasma thickness is equal to p i , are explained by a physical model.
