Coupling effects in low-symmetry planar split-ring resonator arrays
We introduce a particular low-symmetry (point group of unit cell C1) planar periodic arrangement of magnetic split-ring resonators that acts as an effective optical wave plate. We show that this behavior specifically results from the in-plane interactions among the individual split-ring resonators. Measured normal-incidence transmittance and conversion spectra of gold-based samples fabricated via electron-beam lithography show fundamental resonances at around 235 THz frequency (1275 nm...[Show more]
