Asymmetric split ring resonators (A-SRRs) are composed of two separate metallic arcs of asymmetric lengths that share the same center-of-curvature. The two arcs interact to produce a very steep slope in the reflection spectrum. We utilize the plasmon resonance hybridization model to understand and describe the working of an A-SRR and produce experimental and simulation results to show that the A-SRR resonances are a "modified linear superposition" of the individual plasmon resonances coming from each of the arcs.
