| Abstract: | A formula of kirchhoff diffraction field of an arbitrary aperture is deduced in the vertical incidence of the spherical electromagnetic wave, and then a method named the Multiple|Complex|Gauss| Legendre integral is applied to solve the difficulties of the numerical calculation in the field's multiple integral. The new method has been proved efficient in practical use with such virtues: high integral precision, simple program, rapid calculation. It can meet the demands of the multiple integral calculation. |
| Keywords: | spherical electromagnetic wave arbitrary aperture Kirchhoff diffraction field method of Multiple|Complex|Gauss|Legendre integral |
