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 metamaterials, the magnetic response is mainly driven by the incident electric field. Here, we fabricated vertical split-ring resonators (VSRRs) which behave as magnetic metamolecules...
We present vertical split-ring resonators (VSRRs) which behave as magnetic metamolecules sensitive to both the incident electric and magnetic fields upon excitation. A couple of potential applications such as VSRR-based highly sensitive refractive-index sensor and metasurface for light manipulation in optical communication frequency will also be demonstrated.
We demonstrate a new electromagnetic mechanism of plasmon induced transparency (PIT) in three dimensional plasmonic meta-molecules at optical frequency region. Using double electron beam exposure lithography, three erected U-shape gold nano rings are integrated in a unit cell with 600 nm periodicity both in x and y directions on a fused silica substrate. By breaking geometrical symmetry, the bright...
