DENG Xiao-jiu, WU Ben-ke
CHINESE JOURNAL OF COMPUTATIONAL PHYSICS
2001, 18 (3):
211-214.
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.
