Abstract

When a perfectly electrically conducting two-dimensional scatterer, which is smooth except at a finite number of sharp corner points, is illuminated by an E-polarised electromagnetic plane wave, the surface current density exhibits singularities at those corner points, whilst in the H-polarised case the surface density exhibits singularities in its derivative at those points. Once the corners are rounded, the surface density becomes nonsingular. It is of physical interest to examine the impact of this rounding upon the surface current and other observed physical quantities such as the far-field, as the rounding becomes more pronounced.
