In this work, we present a semi-numerical approach that enables the efficient design of hybrid phase-shifting surfaces (PSSs) with significantly reduced computational cost. Traditional design approaches of PSSs with N number of layers that have M different variations of conductive patches, must utilize MN full-wave simulations. Our approach achieves a great reduction of this computational effort only requiring N× M full-wave simulations by decomposing a PSS into N number of cascaded networks, and utilizing the multiplication property of ABCD parameters. To validate the accuracy of our method, a hybrid PSS is designed to steer the beam of a circularly polarized holographic metasurface antenna (HMA) that operates at 30 GHz. Comparisons between our analytical results and full-wave simulations for our beam steerable antenna demonstrate an angular error of less than 1°.
