Abstract: The interconnection of polarization and phase in electromagnetic scattering process has attracted both fundamental and practical interest. Here we propose the principle and experimental demonstration of a scattering- control mechanism based on the simultaneous control of polarization and phase via a continuously shaped planar metasurface. Under circularly polarized illumination, the scattering is redirected to off-specular direction, leading to significant reduction of the scattering cross section. Theoretical investigation shows that the underlying physical mechanism is the spin-dependent phase modulation in the anisotropic scattering process. Our approach would provide valuable guidance for the full control of electromagnetic wave for diverse applications.
