Abstract
We analyze the time harmonic Maxwell's equations
in a geometry containing perfectly conducting split rings. We
derive the homogenization limit in which the typical size
of the rings tends to zero. The split rings act as resonators
and the assembly can act, effectively, as a magnetically active
material. The frequency dependent effective permeability of
the medium can be large and/or negative.
