Caption
An artist depiction of the Airy nondiffracting beam generated using flat optical element. In (a) the Airy beam self-heals after passing through an obstacle. In (b) the Airy beam illuminates a sample with different number of stacked graphene layers deposited on silicon substrate. Underneath the pictures of graphene layers recorded intensity distributions for each sample are depicted and orientation is denoted by letters x and y.
