    • Negative refraction and subwavelength focusing using photonic crystals 

      Ozbay, E.; Aydin, K.; Alici, K. B.; Guven, K. (2005)
      We review certain novel optical properties of two-dimensional dielectric photonic crystals (PCs) which exhibit negative refraction behavior. We investigate two mechanisms which utilize the band structure of the PC and lead ...
    • Subwavelength resolution in a two-dimensional photonic-crystal-based superlens 

      Cubukcu, E.; Aydin, K.; Ozbay, E.; Foteinopolou, S.; Soukoulis, C. M. (American Physical Society, 2003)
      The experimental and theoretical demonstration of a single-beam negative refraction and a superlensing effect in 2D photonic crystals was reported. As such, negative refraction was observed for the incidence angles of >20°. ...
