Abstract

We propose a reconfigurable electromagnetic metamaterial device driven by magnetic fields. A field-driven reconfigurable metamaterial component (FD-RMC) consisting of periodic channels and compound liquid medium is fabricated. The transition of the electromagnetic metamaterial device from an absorbing state to a frequency-selective state is realized by placing the FD-RMC filled with a compound liquid medium in a gradient magnetic field. The effective bandwidth of the FD-RMC is 14.1 GHz (3.9–18 GHz) in the absorbing state, and it exhibits obvious filtering characteristics at 7.8 GHz in the frequency-selective state. Repeated testing showed that the FD-RMC has great repeatable reconfigurability.
