Abstract: Using the angular spectrum representation,the homogeneous and evanescent waves in near-field diffraction of a small aperture are examined.As an example,the diffraction of a plane wave by a circular aperture is considered in detail,and some new results have been obtained.

Key words: near-field diffraction, Fourier optics, homogeneous waves, evanescent waves
