摘要
Abstract
The integral representation of two dimensional FRFT isproposed.On the base of the definition of one-dimensional fractional Fourier transform (FRFT),After analyzing the radiated field of an aperture current distribution, the relationship between this field and the 2D-FRFT of the current distribution is presented.Discussions on two limitation cases show that the 2D-FRFT can provide a uniformly effective tool for the computation of aperture radiation both in Fresnel and in Fraunhofer regions.关键词
