Abstract :
We have demonstrated direct measurement of the time-dependent terahertz (THz) magnetic near-field of split-ring resonators (SRRs) by using Terahertz Time-Domain Spectroscopy (THz-TDS). We also show that the local magnetic field in these structures is strongly enhanced relative to the THz magnetic field incident on these structures.
