Transmission through split ring resonator SRR structures loaded with capacitors is investigated both experimentally and numerically. Magnetic resonance frequency m is observed to shift to lower frequencies when capacitors are mounted to the various capacitive regions of the SRR structure. The amount of change in m depends strongly on the place where the capacitors are loaded. The magnetic resonance is obtained at 0.99 GHz with subwavelength SRR size of /42 when the capacitor C=2.2 pF is integrated at the split region of the outer ring.
