Simulated plasmonic activity is reported for a series of Au nanoring antennae with 1–5 splits in their geometry. The rings have a radius of 75 nm and splits of 3–6 nm. By controlling the size of the splits, their location and the radius of the ring structure, we can control the number, intensity and frequency of the plasmonic hotspots.
