Nonlinear geometric phase gradient metasurfaces beyond the dipole approximation

Gennaro, Sylvain D.; Li, Yi; Maier, Stefan A.; Oulton, Rupert F.

In this work, we identify the role of higher order antenna’s modes on a metasurface’s Pancharatnam – Berry phase by investigating second harmonic light scattering from two metasurfaces exhibiting dipolar and quadrupolar radiation.
