Abstract
The authors demonstrate that staircased approximations to curved or oblique electromagnetic interfaces yield poor accuracy unless the user has truly unlimited computer resources for two simple geometries: a conducting strip and a circular conducting cylinder. Conformal meshing reduces by a factor of four the resolution required in each direction. A conformally meshed circular cylinder model yields good radar cross section (RCS) predictions with only eight cells per wavelength
