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. © 2007 Wiley Periodicals, Inc.
