Abstract
To reduce strong diffractive fields at the baseline edge of a metal body which is reflective of electromagnetic radiation, a substrate substantially transparent to the radiation is placed contiguous to that edge. Conductive reflective elements are carried on an exposed surface of the substrate, in a pattern such that reflection decreases and transparency increases from the baseline toward the terminal edge of the substrate. Thus the diffractive field is gradually reduced.
