    • Asymptotic wave-like modeling of dielectric lenses 

      Yurchenko, V. B.; Altıntaş, Ayhan (IEEE, 2007)
      We propose asymptotic wave-like approximations for the accurate modeling of dielectric lenses used in quasi-optical systems of millimeter, submillimeter, and infrared wave applications. For the comparison, we obtain an ...
    • Composite chiral metamaterials with negative refractive index and high values of the figure of merit 

      Li, Z.; Caglayan, H.; Alici, K. B.; Kafesaki, M.; Soukoulis, C. M.; Özbay, Ekmel (Optical Society of America, 2012)
      A composite chiral metamaterial (CCMM) is designed and studied both numerically and experimentally. The CCMM is constructed by the combination of a continuous metallic wires structure and a purely chiral metamaterial (CMM) ...
    • Negative refraction and superlens behavior in a two-dimensional photonic crystal 

      Moussa, R.; Foteinopoulou, S.; Zhang, L.; Tuttle, G.; Guven, K.; Özbay, Ekmel; Soukoulis, C. M. (American Physical Society, 2005)
      We experimentally and theoretically studied a left-handed structure based on a photonic crystal (PC) with a negative refractive index. The structure consists of triangular array of rectangular dielectric bars with dielectric ...
