Vortex pinning and rectification effect in a nanostructured superconducting film with a square array of antidot triplets
(color online) Schematic view of thin superconducting strip with array of holes. (a) One array geometry is characterized by two distances A (the period of the antidot triplets), B (the spacing among the antidot triplets), and the hole diameter D (denoted by A–B–D). (b) Another array geometry is characterized by the square period A and the hole diameter D (denoted by A–D).
