Complex source representation of time harmonic radiation from a plane aperture

Developed here is a new complex source representation for time harmonic radiation from a plane aperture which is the Kirchhoff's spatial convolution formula of a complex plane aperture with the complex aperture field being the analytic extension of the original aperture field. A systematic study for a one-dimensional linearly phased cosine aperture distribution confirms the effectiveness of the new method in the simulation of the time harmonic radiation.<
