摘      要：Planar graphene metalens has demonstrated advantages of ultrathin thickness(200 nm),high focusing resolution(343 nm)and efficiency(32%)and robust mechanical strength and ***,diffraction-limited imaging with such a graphene metalens has not been realized,which holds the key to designing practical integrated imaging *** this work,the imaging rule for graphene metalenses is first derived and theoretically verified by using the Rayleigh-Sommerfeld diffraction theory to simulate the imaging performance of the 200 nm ultrathin graphene *** imaging rule is applicable to graphene metalenses in different immersion media,including water or *** on the theoretical prediction,high-resolution imaging using the graphene metalens with diffraction-limited resolution(500 nm)is demonstrated for the first *** work opens the possibility for graphene metalenses to be applied in particle tracking,microfluidic chips and biomedical devices.
