Abstract

Asymmetric split ring resonators (A-SRRs) are formed when two separate metallic arcs of different lengths share the same centre-of-curvature. The resonances of the two arcs interact to produce steep slopes in the reflection spectrum. Due to their size they are also known as nano antennas. By depositing very thin films of poly-methyl-methacrylate (PMMA), a shift in resonance reflection spectra is obtained. Similarly, it is known that the spectral position of the A-SRR resonances can be tuned with size.
