Abstract: We measure the Casimir force between a gold sphere and a silicon plate withnanoscale, rectangular corrugations with depth comparable to the separationbetween the surfaces. In the proximity force approximation PFA, both the topand bottom surfaces of the corrugations contribute to the force, leading to adistance dependence that is distinct from a flat surface. The measured Casimirforce is found to deviate from the PFA by up to 15%, in good agreement withcalculations based on scattering theory that includes both geometry effects andthe optical properties of the material.
