    • Observation of negative refraction and focusing in two-dimensional photonic crystals 

      Özbay, Ekmel; Bulu, M.; Guven, K.; Caglayan, H.; Aydin, K. (Institute of Physics Publishing Ltd., 2006)
      We experimentally and theoretically demonstrate the negative refraction and focusing of electromagnetic (EM) waves by twodimensional photonic crystal slabs at microwave frequencies. The negative refraction is observed both ...
    • Physics and applications of photonic crystals 

      Özbay, Ekmel; Bulu I.; Aydin, K.; Caglayan H.; Guven, K. (Nanotechnology Research Center NANOTAM, 2004)
      In this article, we investigate how the photonic band gaps and the variety of band dispersions of photonic crystals can be utilized for various applications and how they further give rise to completely novel optical ...
    • Simulation and micro-fabrication of optically switchable split ring resonators 

      Gundogdu, T. F.; Gökkavas, M.; Güven, K.; Kafesaki, M.; Soukoulis, C. M.; Özbay, Ekmel (Elsevier BV, 2007-10)
      The effect of conductivity variation as a proposed method for the investigation of photoconductive switching properties of split ring resonators (SRRs) is simulated. Three different systems that are applicable under certain ...
