Abstract

Vertical split-ring resonators (VSRRs) were fabricated which behave as magnetic metamolecules sensitive to both incident electric and magnetic fields with the stronger induced magnetic dipole moments upon excitation in comparison to planar SRRs. Using these metamolecules with different spacing in VSRR dimers, we investigate the hybridization of the magnetic plasmon modes associated with each constituent VSRRs. We found that plasmon coupling can be precisely controlled by varying the gap separation between VSRRs. The resulting wide tuning range of these hybrid modes offers the possibility of developing frequency selective functional devices such as sensors and filters based on plasmon coupling with high sensitivity.
