Abstract

The magnetic coupling effects of compact two-pair, three-pair and four-pair split-ring resonators (SRRs) have been investigated both numerically and experimentally in relation to the time-varying H-field of a microstrip transmission line (TL). As the number of SRRs increases from a two-pair to a four-pair configuration, the magnetic coupling effects are enhanced and this is manifested in the stopband and quality factor characteristics in the S 21-parameter. Further, we note that the measured result of a four-pair SRR in the array drops to -42 dB at around 10.8 GHz. This is a good characteristic that can efficiently prohibit signal propagation in the vicinity of the resonant frequency. Finally, the practical implications of these results are discussed.
