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. 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. 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, ...
