Metamaterial Superlenses for the Visible and UV
A new design for metamaterial lenses allows the operating frequency to be scaled almost to the ultraviolet.
A new design for metamaterial lenses allows the operating frequency to be scaled almost to the ultraviolet. The work, by Muhammad I. Aslam and Durdu Guney at Michigan Technological University (U.S.A.), is an extension of previous studies that only reached the long-wavelength edge of the visible spectrum (Phys. Rev. B, doi: 10.1103/PhysRevB.84.195465). Visible or UV lenses made using these technologies would enable optical microscopes with resolutions down to 100 nm, below the diffraction limit.
