Analysis of Curved Metasurfaces Based on Method of Moments

With research of curved metasurfaces gaining more attention, adequate analysis methods are needed to allow for an efficient design of such structures. Previous works dealt with specific canonical problems, such as those with cylindrical geometry, which were mostly analyzed using Mode Matching approach. In this paper we present an analysis based on Method of Moments which can be used for any generally-curved metasurface structure situated in free-space, or for metasurfaces embedded in canonical multilayer supporting structures (e.g. spherical or cylindrical). We implement a solver for this method and verify the results against other computational approaches, as well as against measurements of a developed antenna pattern-shaping metasurface.
