【Abstract】 A new method of designing X-ray supermirror is presented. The design is based on the well-known Frensnel equations and simplex optimization, which allow the design of X-ray supermirror with different requirement. A convenient method to decide the number of the layers of multiplayer is brought up, many design results of W/C multilayers, and their reflectance profiles with different angle range for Cu K(radiation are given. The saturation effect, resultedfrom the interfacial roughness of the multiplayer, also is emerged in the design of X-ray supermirror, and is performanted. It is proved that the performances of multilayers designed using this method are superior to those designed using existing methods.更多还原
