Figure 4: Scattering properties of the SBR with varied cut parameters.
From: Split-ball resonator as a three-dimensional analogue of planar split-rings
The dependence of the scattering efficiency of the SBR on (a) the cut depth for a fixed cut width of 20 nm and (b) on the cut width at a fixed cut depth of 100 nm. The incident plane wave is directed from top of the SBR with light polarization perpendicular to the cut. The gold sphere diameter is 200 nm.
