    • Photonic Crystal based spatial filtering 

      Colak, E.; Çakmak, A. Özgür; Serebryannikov, Andriy E.; Özbay, Ekmel (IEEE, 2009)
      Two dimensional Photonic Crystal structure is used to achieve spatial filtering. The structure provides bandstop filtering in the incident angle range of 18° to 38°. The transmission is close to unity outside of this range. ...
    • Spatial filtering using dielectric photonic crystals at beam-type excitation 

      Colak, E.; Cakmak, A. O.; Serebryannikov, A. E.; Özbay, Ekmel (American Institute of Physics, 2010-12-06)
      Spatial filtering is demonstrated at beam-type excitations by utilizing finite thickness slabs of two-dimensional dielectric photonic crystals (PCs) showing exotic Fabry-Perot resonances that are preserved over a wide range ...
    • Spatial filters based on EBG structures with anisotropic-like dispersion 

      Serebryannikov, A.E.; Cakmak, A.O.; Çolak, Evrim; Özbay, Ekmel (IEEE, 2010)
      Bandpass and bandstop spatial filters based on the dielectric-rod EBG structures are proposed and validated for the frequency range from 18 to 25 GHz. The obtained experimental results are well consistent with the theoretical ...
