    • Experimental analysis of true left-handed behaviour and transmission properties of composite metamaterials 

      Guven, K.; Aydin, K.; Özbay, Ekmel (Elsevier, 2005-12)
      We report the true left-handed transmission of a composite metamaterial (CMM) consisting of periodically stacked split-ring resonator (SRR) and wire elements. The negative permeability (μ < 0) gap is demonstrated explicitly ...
    • Metamaterials with negative permeability and negative refractive index: Experiments and simulations 

      Özbay, Ekmel; Guven, K.; Aydin, K. (Institute of Physics Publishing Ltd., 2007)
      We report the transmission characteristics of split-ring resonator and left-handed metamaterials (LHM) in the microwave frequency regime. A left-handed transmission band is observed at the frequencies where both dielectric ...
    • Negative refraction and imaging beyond the diffraction limit by a two-dimensional left-handed metamaterial 

      Özbay, Ekmel; Aydin, K. (Elsevier BV, 2008)
      We report our experimental results on two-dimensional left-handed metamaterials (LHM) exhibiting negative refraction and subwavelength imaging. Transmission and reflection spectra of LHM are studied and a left-handed ...
    • 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 ...
    • Physics and applications of photonic nanocrystals 

      Ozbay E.; Guven K.; Aydin K.; Bayindir M. (2004)
      Photonic nanocrystals are periodic dielectric or metallic structures having photonic bands in analogy to electronic bands of semiconductors. The presence of photonic band-gaps, where the propagation of photons of certain ...

      Özbay, Ekmel; Guven, K.; Aydın, K.; Bayindir, M. (Inderscience Publishers, 2004)
      Photonic nanocrystals are periodic dielectric or metallic structures having photonic bands in analogy to electronic bands of semiconductors. The presence of photonic band-gaps, where the propagation of photons of certain ...
    • Review of experimental studies on microwave left-handed metamaterials 

      Özbay, Ekmel; Aydın, Koray (American Institute of Physics, 2007)
      We review experimental studies on left-handed metamaterials operating at microwave frequencies. Left-handed transmission is obtained from a composite metamaterial consisting of periodic split ring resonator and wire arrays. ...
