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.
