Abstract

A family of coupled nano-strips with varying dimensions is fabricated to obtain optical magnetic responses across the whole visible spectrum, from red to blue. The proposed approach provides one with a universal building block and a general recipe for producing controllable optical magnetism for various practical implementations.
