Abstract: We introduce a novel concept to nano-photonics, namely stereometamaterials. As model system of stereometamaterials, we theoretically and experimentally study meta-dimers, which consist of a stack of two identical split-ring resonators[1] in each unit cell with various twist angles. We demonstrate that the interplay between electric and magnetic interactions plays a crucial role for the optical properties[2]. Specifically, the influence of higher-order electric multipoles becomes clearly evident. The twisting of stereometamaterials paves the road towards engineering of complex plasmonic nanostructures with tailored electric and magnetic interactions.
