Electromagnetic scattering by a right-angled lossy dielectric wedge at normal incidence is considered in detail. The lossy dielectric material of the wedge is simulated using second-order impedance boundary conditions on its faces. The Maliuzhinets method is employed to obtain the total exterior field. A high-frequency asymptotic approximation of the Sommerfeld integral is carried out to obtain a UTD expression for the total field. The predictions are validated against experimental measurements taken in a controlled laboratory environment. A comparison with the widely used heuristic UTD diffraction coefficient of Luebbers is presented and the validity of the latter coefficient is discussed.
