A free‐standing phase and amplitude shifting surface (PASS) composed of four conductive layers separated by electrically thin dielectric sheets is presented in this article.This surface can be used for applications in which one must control both the phase and amplitude of electromagnetic waves propagating through it at every location over the aperture. The PASS provides a simple and efficient technique for manipulating the radiation pattern from a feed antenna for beam shaping applications. As a proof of concept, the technique is applied in the design of a flat‐topped shaped beam antenna. © 2012 Wiley Periodicals, Inc.
