Metamaterial fibres for subdiffraction imaging and focusing at terahertz frequencies over optically long distances
Using conventional materials, the resolution of focusing and imaging devices is limited by diffraction to about half the wavelength of light, as high spatial frequencies do not propagate in isotropic materials. Wire array metamaterials, because of their extreme anisotropy, can beat this limit; howev...
