Magnetoinductive waves in arrays of split-ring resonators

We study experimentally the propagation of linear magnetoinductive waves in arrays of split-ring resonators with different orientation and spacing. We summarize our experimental results characterizing the effect of coupling of individual elements in magnetic composite metamaterials. We observe the band broadening due to the excitation of magnetoinductive waves which should impose some limitatio...

Numerical Investigation of Light Scattering off Split-Ring Resonators

It seems to be feasible in the near future to exploit the properties of left-handed metamaterials in the telecom or even in the optical regime. Recently, split ring-resonators (SRR’s) have been realized experimentally in the near infrared (NIR) and optical regime. 2 In this contribution we numerically investigate light propagation through an array of metallic SRR’s in the NIR and optical regime...

Spectral imaging of individual split-ring resonators.

We report on spectral imaging within individual silver split-ring resonators (SRRs) operating in the near infrared-visible range. We classified the optical eigenmodes from the measurement of their energies and nanometer scale spatial distributions. They are plasmonic standing waves that show great similarities with that of nanoantennas. We, however, evidenced marked differences in the near-fiel...

Nonlinear properties of split-ring resonators.

In this letter, the properties of split-ring resonators (SRRs) loaded with high-Q capacitors and nonlinear varactors are theoretically analyzed and experimentally measured. We demonstrate that the resonance frequency f(m) of the nonlinear SRRs can be tuned by increasing the incident power. f(m) moves to lower and higher frequencies for the SRR loaded with one varactor and two back-to-back varac...
