This paper presents a design method of fraction Fresnel zone plates(FFZPs), a new kind of binary optics elements, by using the vibration vector method. The anti-diffraction character of fraction Fresnel zone plates was investigated. The propagation distance of radiation beams with high intensity can be prolonged by using FFZPs.
