Abstract
In the past decade, a number of interesting designs have been proposed to generate artificial magnetism at optical frequencies using plasmonic metamaterials, but owing to the planar configurations of typically fabricated meta-molecules that make up the metamaterials, the magnetic response is mainly driven by the electric field of incident electromagnetic wave.In this work, we have fabricated 3D split-ring resonators (SRRs) [1] which allowed us to study how incident electromagnetic fields interact with these 3D SRRs and to reveal the plasmon coupling between closely spaced SRR dimers.
