Abstract:

The effect of conductivity variation as a proposed method for the investigation of photoconductive switching properties of split ring resonators SRRs is simulated. Three different systems that are applicable under certain fabrication andor optical excitation conditions are described. The simulated transmission spectrum indicates that for a large range of dark conductivity values, complete switching of the SRR resonance is possible. One of the simulated systems, involving split ring resonators on Si substrate, was fabricated and characterized. The transmission spectrum of that system was measured, with the Si in its high-resistivity state, and a 60 dB dip between 108 and 115 GHz, due to SRRs magnetic resonance, was observed.
