Magnetization waves in split-ring-resonator arrays: Evidence for retardation effects
We excite low-symmetry planar arrays of nanoscale magnetic split-ring resonators oscillating at around 200 THz frequency under oblique incidence of light. Due to the in-plane coupling of split-ring resonators, classical magnetic-dipole waves result in the plane. We measure the dispersion relation of "antiferromagnetic" and "ferromagnetic" modes, revealing backward waves and a wave-vector-dependent damping. The latter provides evidence for retardation effects, which play no role in the...[Show more]
