摘要：
Transmission through split ring resonator (SRR) structures loaded with capacitors is investigated both experimentally and numerically. Magnetic resonance frequency (omega(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 omega(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 lambda/42 when the capacitor (C=2.2 pF) is integrated at the split region of the outer ring.
