摘要
In this paper, we present numerically and experimentally the negative magnetic response of magnetic metamaterial elements, i.e., single and double split-ring resonators (SRRs), excited by a high-impedance microstrip line at microwave frequencies. Both SRRs exhibit a good resonance peak, as well as a negative magnetic response. The corresponding negative bandwidths of the single and double SRRs are Delta f(S) = 800 MHz and Delta f(D) = 400 MHz, respectively. According to the obtained results, a single SRR is a more effective configuration for simultaneously realizing negative magnetic permeability with a higher Q value than a double SRR in the current system.
