| Abstract: | The scatter field, which produced by the gratings which made of limitless length metal cylinders, is studied. On the basis of theoretic analysis, a FORTRAN 77 programme is compiled for the scatter equation. As anexample, the near scatte field of the gratings is calculated with the computer, and some laws of the scatter field are described. The programme presented is universal. It is adaptable to all kinds of finit gratings and suitable for both near and far field. |
