We report on experimental and numerical studies on the coupling efiect of a single split ring resonator (SRR) and its mirror image inside an X-band hollow waveguide. It is shown that, for single SRR with gap bearing side perpendicular to E fleld, the magnetic resonance exhibits red/blue shift as SRR moves to the gap facing/backing waveguide edge, due to the capacitance and magnetic dipoles coupling efiect between original SRR and its mirror image, respectively. Furthermore, electric dipole interplay dominates the coupling efiect between SRR and its image when SRR has the gap bearing side parallel to the E fleld, although SRR is excited by E and H fleld simultaneously.
