“…However, there remain three major differences between the two design algorithms. The first major difference is that the equivalent currents can also produce evanescent waves (equivalent to surface waves in the context of the metasurface structure [4], [19]). These waves are explicitly ignored in the PWS-based algorithm by the choice of basis functions.…”

“…This requires that local power conservation (LPC) [1], [2] is met at each unit cell along the metasurface. To help meet the LPC condition, we can redistribute the power by exciting auxiliary surface waves [3], [4], utilizing cavity methods [5], or by employing a cascaded metasurface pair [6], [7]. In the case of the latter, the goal is to find the fields in the bounded space between the metasurface pair that satisfy the LPC condition for a desired field transformation.…”

<p>In this paper, we consider two design procedures for a cascaded metasurface pair. For a particular application, we present and evaluate data from simulations and experiments. We discuss the details and limitations of the two design algorithms, the fabrication process, and the measurement procedure. In particular, we highlight difficulties with respect to the measurement and analysis, as well as the techniques used to address these difficulties.</p>
