| Abstract: | A computing method with computer for the Fresnel diffraction of rectangular aperture is proposed.By transforming the integral of the Fresnel diffraction,the formula of the Fresnel diffraction for rectangular aperture is expressed by the Fresnel integral.Combining the virtue of the MATLAB and MAPLE,we use MAPLE integral order in the MATLAB language to carry out the numerical computing of the Fresnel diffraction and present the result of the numerical computing.This method is applied to compute the Fresnel diffraction of the single slot and half plane. |
