The Kontorovich-Lebedev transform is used to obtain an exact solution for the scattering from a linearly tapered resistive half plane for E polarized plane wave illumination. Uniform and nonuniform asymptotic results for the scattered field are obtained, which provides the ray optical interpretation of the calculated scattered field including the edge diffraction pattern for various values of resistivity gradient. The edge diffraction approaches that of the conducting half plane as the gradient approaches zero and that of an isolated wire as the gradient approaches infinity. Calculated interference fringes of the scattered field in the illuminating region for the varying resistive half plane differ significantly from those of either the conducting or uniform resistive half plane.
