    • Characterization and applications of negative-index metamaterials 

      Aydın, Koray (Bilkent University, 2008)
      Metamaterials offer novel electromagnetic properties and promising applications including negative refraction, flat-lenses, superlenses, cloaking devices. In this thesis, we characterized the negative-index metamaterials ...
    • Focusing of electromagnetic waves by a left-handed metamaterial flat lens 

      Aydin, K.; Bulu, I.; Ozbay, E. (Optical Society of America, 2005-10-31)
      We present here the experimental results from research conducted on negative refraction and focusing by a two-dimensional (2D) left-handed metamaterial (LHM) slab. By measuring the refracted electromagnetic (EM) waves from ...
    • The left hand of electromagnetism : metamaterials 

      Alıcı, Kamil Boratay (Bilkent University, 2010)
      Metamaterials are artificial periodic structures whose electromagnetic response is solely dependent on the constituting unit cells. In the present thesis, we studied unit cell characteristics of metamaterials that has ...
    • Negative refraction using true left-handed metamaterials 

      Aydın, Koray (Bilkent University, 2004)
      Left-handed materials and negative refraction attracted a great amount of attention in recent years due to their unique physical properties. It is possible to obtain a left-handed material by combining a novel artificial ...
    • Optical properties of metamaterial-based devices modulated by a liquid crystal 

      Karaomerlioglu, F.; Mamedov, A. M.; Ozbay, E. (Springer Berlin Heidelberg, 2014)
      Due to the fact that it is possible to manipulate light with photonic crystals (PCs), PCs hold a great potential for designing new optical devices. There has been an increase in research on tuning the optical properties ...
    • Sub-wavelength resolution in a photonic crystal superlens 

      Çubukçu, Ertuğrul (Bilkent University, 2003)
      Materials that can bend light in the opposite direction to normal (’left-handed’ materials) reverse the way in which refraction usually works-this negative refractive index is due to simultaneously negative permeability ...
