Metamaterials with zero phase delay

摘要：

　　During the early years of research into metamaterials, some interest has shifted towards the realization of materials that exhibit zero or near-zero refractive index.A refractive index of zero implies that light enters a state of quasi-infinite phase velocity and infinite wavelength.Instead of strong resonance mechanism in metamaterials, the physical phenomenon of PhC is based on the special dispersion relations of photonic bands with weak loss.Several different metamaterials to realize zero phase delay are introduced in this paper.Their remarkable properties should have significant technological applications in photon delay lines with zero phase difference, information-processing devices, new optical phase control and measurement techniques.
