Abstract
A reflector () reflects energy emitting from an energy source () and focuses and directs it to a target. An aperture stop or suppressor disk () is positioned between the energy source () and target. The outer periphery of the aperture stop or suppressor disk () is an irregular curve (FIGS.and). This shape of the periphery prevents diffraction enhancement to the direct wave.
