Incremental diffraction coefficients for the extended physical theory of diffraction

摘要

The extended physical theory of diffraction (EPTD), which is an extension of Ufimtsev's (1962) theory to aperture integration, is formulated in terms of incremental diffraction coefficients (IDC). Closed-form expressions for these coefficients are derived. The utility of the derived IDC is exemplified in a calculation of the cross-polar pattern of a parabolic reflector.
