    Abstract

    The performance of Fresnel zone plates having polygonal boundaries between zones has been studied for polygons with a low number of sides. An optimized polygonal shape has been analytically defined by, minimizing the mismatched area between the circular and the polygonal pseudo-Fresnel zones. The square polygon has been analyzed in more depth than the others because of its simple symmetry. (c) 2007 Wiley Periodicals, Inc.
