title: Left-handed media and homogenization of photonic crystals.
abstract: Using homogenization theory, we derive the effective permittivity and permeability of a wire-mesh photonic crystal from first principles. We show that this structure does not lead to a left-handed medium when it is embedded in a matrix with a negative mu, but that resonators in a medium with a negative epsilon do form a left-handed medium in the correct range of frequencies.
