Magnonic crystals (MCs), or composite materials with periodically arranged magnetic inclusions, can have properties not found in bulk samples. In the long-wave limit the MC can be characterized by its effective continuous properties. We calculate the effective permeability of two-dimensional MCs to estimate their potential usage as negative index metamaterials.
