A study of a low-profile hybrid Wood zone plate fishnet metamaterial lens working at f = 99 GHz is presented. The use of fishnet metamaterial with effective refractive index close to zero (n = 0.51) as a medium for Fresnel zones allows to reduce the reflections from the metalens and increase the overall efficiency, while maintaining low profile, low cost and ease manufacturing. The performance of metalens was analyzed numerically and confirmed experimentally,demonstrating a good agreement.
