Radiation patterns have been computed for an axial slot on an infinite circular cylinder coated with a radially inhomogeneous plasma sheath. The relative dielectric constant was assumed to have three types of radial dependence: monotonic with a minimum at the inner edge of the sheath but with no portion of the sheath below plasma resonance; monotonic with the inner portion of the sheath below plasma resonance; parabolic with a minimum within the sheath and the inner portion of the sheath below resonance. The radial wave functions within the sheath are obtained in the form of infinite series. The resulting radiation patterns are found to be sharply directed in the forward direction relative to the equivalent free-space pattern. These sharply forward-directed patterns are consistent with the interpretation of a "diffusion-type" process within layers of the sheath below cutoff and a predominantly "refraction-type" process within layers above cutoff.
