Abstract

The magnetic coupling effect of the two-pair, three- pair, and four-pair square split-ring resonators (SRRs) array is studied both numerically and experimentally using microstrip line. As the square SRRs array increases, the magnetic coupling effect is enhanced. This is manifested by a dip in the transmission coefficient (S21). Particularly, the four-pair square SRRs array falls down about 42 dB at 10.8 GHz. For small separation distance (0.2 mm) between square SRRs and microstrip line, very strong coupling, leading to sharp resonances with quality factors about 240 is observed.
