Abstract

A numerical study of the scattering of a plane wave by an infinite cylindrical structure with corners with E-polarized, H-polarized and impedance loaded boundary conditions is reported. An examination of the difference of the far-field patterns generated by the cornered structures and those generated when the corners are rounded shows that this difference is O((kρ)^m) as the radius of curvature ρ of the rounded corner decreases.
