Abstract :
FDTD simulations of periodic split ring resonators in highly doped silicon show multiple THz surface plasmon resonances (SPR). The SPR frequency position may be tuned by modifying the split ring wall width, split angle and outer radius. These frequency tunable resonators are efficient THz detectors.
