Recent advances in nanophotonic structures covering both photonic crystals (PhC) and metamaterials are reviewed. Useful properties have been obtained metal-based planar Split Ring Resonator (SRR) structures at infra-red optical frequencies and wo

Three-dimensionally periodic (3D) photonic crystals that operate in the optical frequency domain have become a concrete reality – and evidence of full photonic bandgap behaviour has been demonstrated reasonably convincingly. Techniques have been
