DOI: 10.1093/ptep/ptz008
Abstract: We study the negative refractive index in cubic noncentrosymmetric superconductors. We consider the Maxwell equations under the Meissner effect, and magnetoelectric effect arising due to broken inversion symmetry. We derive dispersion relations of electromagnetic waves,… read more here.

DOI: 10.1364/ome.8.001916
Abstract: Development of continuous wave (CW) sources has recently advanced in various frequencies of the terahertz waveband. However, there are few materials suitable for the terahertz waveband, and attractive materials are eagerly awaited. Metamaterials with artificial… read more here.
