Proposed mechanism to enhance optical gradient forces between two dielectric slab waveguides. A metamaterial cladding indicated by split-ring resonators is derived from a folded coordinate transformation to reduce the distance between the two waveguides (shown in plain gray) perceived by light. Selected for an Editors' Suggestion and a Synopsis in Physics.
