On the resonances and polarizabilities of split ring resonators
Description
In this paper, the behavior at resonance of split ring resonators SRRs and other related topologies,
such as the nonbianisotropic SRR and the broadside-coupled SRR, are studied. It is shown that these
structures exhibit a fundamental resonant mode the quasistatic resonance and other higher-order
modes which are related to dynamic processes. The excitation of these modes by means of a
properly polarized time varying magnetic and/or electric fields is discussed on the basis of resonator
symmetries. To verify the electromagnetic properties of these resonators, simulations based on
resonance excitation by nonuniform and uniform external fields have been performed. Inspection of
the currents at resonances, inferred from particle symmetries and full-wave electromagnetic
simulations, allows us to predict the first-order dipolar moments induced at the different resonators
and to develop a classification of the resonances based on this concept. The experimental data,
obtained in SRR-loaded waveguides, are in agreement with the theory and point out the rich
phenomenology associated with these planar resonant structures.
