Transmission coefficient of a plane electromagaetic wave into a cold, inhomogeneous, magnetized, deuteriuma plasma half-space and its eventual absorption at the lower-hybrid layer is computed parameters. It is found that TM (transverse magnetic) waves incident at small angles with the vacuum -plasma interface couple into the plasma provided that omega / omega /sub ci/ < approximately 20. Assuming that coupling to the lowerhybrid resonance in the cold-plasma approximation is an indication of accessibility to the ion-cyclotron- harmonic waves in the hot-plasma case, an alternative statement of the results obtained is that efficient coupling is possible from the second till the twentieth harmonic of the ion gyrofrequency using an antenna that launches TM waves at an approximately grazing incidence on the plasma surface. The most important contribution of this work is the suggestion of simple configurations for coupling rf energy into thermonuclear plasmas. (GE)
