In this work, we present a method that enables the ulta-fast design of phase shifting surfaces (PSS) for various antenna applications. Traditional design approaches utilize full-wave simulations that are extremely time-consuming and computationally expensive. Our approach uses the multiplication property of ABCD parameters of cascaded networks to design N-layer PSSs, which consist of M different variations of conductive patches. Following the proposed approach for designing an N-layer PSS, we only need to perform N × M full-wave simulations instead of NM simulations, which must be performed when the traditional approach is used. Our method's accuracy is studied and validated; specifically, it exhibits a total percentage error of less than 6% for both amplitude and phase.
