Abstract
The scattering of obliquely incident electromagnetic waves by a perfec tly conducting circular cylinder is analyzed. In this paper the accura cy of a high-frequency asymptotic model based on the Uniform Theory of Diffraction (UTD) is investigated by comparing UTD simulations with r esults obtained from the exact eigenfunction solution for plane-wave i ncidence. UTD results are also compared with results from experiments carried out at 50 GHz, for various cylinder radii and for different li near wave polarizations. Excellent agreement between the measurement r esults and the theoretical ones is obtained.
