Design of a wide bandwidth achromatic metalens based on phase change material GST with aperture sharing
This paper proposes the use of aperture sharing synergistic operation in the structure of the metalens, together with the rational selection of the scattering unit size according to the linear relationship between the output phase and frequency of the scattering unit, and the selection of the slope...
