We analyze the time-harmonic Maxwell equations in a complex geometry: many (order) small (order), thin (order), and highly conductive (order) metallic objects are distributed in a domain. We determine the effective behavior of this metamaterial in the limit. For, each single conductor occupies a simply connected domain, but the conductor closes to a ring in the limit. This change of topology allows for an extra dimension in the solution space of the corresponding cell-problem. Even though both original materials (metal and void) have the same positive magnetic permeability, the effective Maxwell system exhibits, depending on the frequency, a negative magnetic response.
