Metamaterials

Guest edited by Choon-Gi Choi (Electronics and Telecommunications Research Institute, South Korea), Hak Ju Lee (Korea Institute of Machinery & Materials, South Korea) and Ortwin Hess (Imperial College London, UK)
Metamaterials are artificial materials with a periodic structure whose bulk properties are determined by the design of this structure.  Metamaterials have been intensively studied over the last two decades because they exhibit fascinating properties (such as negative refraction) which do not exist in natural bulk materials. This thematic series will bring together contributions covering the state-of-the-art in novel metamaterial theory, design, fabrication, characterisation and application. 


  1. Review

    Electro-optic switching in metamaterial by liquid crystal

    Electro-optic switching of reflection and refraction is experimentally demonstrated in metasurface liquid crystal cell. Negative metasurface is fabricated by focused-ion-beam milling, and twisted nematic cells...

  2. Review

    Metamaterials and imaging

    Resolution of the conventional lens is limited to half the wavelength of the light source by diffraction. In the conventional optical system, evanescent waves, which carry sub-diffraction spatial information, ...
