We experimentally investigate the reflection behaviors of negative permeability metamaterials (NPMs) consisting of a periodic array of copper hexagonal split ring resonators (SRRs). Results show that, for the two-dimensional (2-D) NPMs samples, a reflectivity peak with the height of 10 dB appears near the resonance frequency, and the reflectivity is remarkably weak on both sides of the transmission gap; the reflection behaviors of 3-D samples similar to that of the 2-D ones are strongly affected by the lattice constants; the reflection phase increases with the frequency, and an inflexion exists at the resonance frequency of 2-D samples.
