KIRCHHOFF''''s FALTUNG FORMULA OF COMPLEX APERTURE AND COMPLEX RAY SIMULATION OF APERTURE RADIATION
复口径Kirchhoff褶积公式和孔径辐射的复射线束仿真

The Kirchhoff's faltung formula of complex aperture is proposed as a new method for radiation from a plane aperture. It is based on the idea of analytic extension that the original aperture field is extended to a complex plane, and then the Kirchhoff's faltung formula makes up an indirect and rigorous representation of the radiation from a plane aperture. Numerical calculations comfirm its effectiveness and correctness.
