  • Abstract
    The convergence properties of Ludwig´s integration technique are investigated, when applied to physical optics (PO) analysis. It is demonstrated that the rate of convergence is sensitive to the choice of integration grid co-ordinate system. Examples of PO analysis applied to paraboloidal and ellipsoidal reflectors show the reduction in computation time achievable when using a cartesian integration grid rather than a polar grid.
