    • Negative refraction and subwavelength focusing using photonic crystals 

      Özbay, Ekmel; Aydın, Koray; Alici, K. B.; Güven, Kaan (SPIE, 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 ...
