(a) Passive single SRR measurement setup. VNA: Vector Network Analyzer; DUT: Device Under Test. (b) Measured AMR frequencies of single SRRs of different sizes as compared with the HFSS 3D simulation results. Solid curve: power law fitting for the measured data set. Dashed curve: power law fitting for the simulated data sets. Both data sets find the curve fitting to be closely inverse proportional to the ring radius. The measured results also agree very well with the simulated results.
