  • Abstract
    The scattering of plane electromagnetic wave of wave number k by a circular aperture of radius a in an infinitely conducting plane screen of zero thickness and infinite extent is considered. In the limit of large ka and at normal incidence, the ratio of the transmission cross section to the geometrical optical value \\pi a^{2} , is found up to the order (ka)^{-5^{j}2} .
