RCS reduction with conformal metasurfaces.
(a), Schematic of the spin-orbit conversion in the curved metasurface on a metallic cylinder. The insets show the definitions of TE and TM polarizations. (b), Calculated broadband RCS reduction for TE and TM polarizations at normal incidence along y-direction.
