| Abstract: | In the paper,the primary characteristics of Fresnel diffraction of one-dimensional aperture are investigated by Finite Difference Time Domain(FDTD).Firstly,the essential principle and implementation method of FDTD is introduced briefly;then,the law of Fresnel diffraction pattern of one-dimensional aperture is analyzed in theory;finally,the numerical simulation results using FDTD are presented,and these results are coincide with those of the theory. |
