This paper investigates the effective magnetic permeability of an rf superconducting quantum interference device (SQUID) array subjected to an alternating magnetic field, highlighting its potential as a nonlinear magnetic metamaterial. The findings indicate that the system can exhibit negative permeability above the resonance frequency and oscillatory behavior at low field intensities, suggesting practical applications in tunable metamaterials, particularly those controlled by magnetic flux.
