    • Experimental observation of cavity formation in composite metamaterials 

      Caglayan H.; Bulu I.; Loncar, M.; Özbay, Ekmel (Optical Society of American (OSA), 2008)
      In this paper, we investigated one of the promising applications of left-handed metamaterials: composite metamaterial based cavities. Four different cavity structures operating in the microwave regime were constructed, and ...
    • Non-ideal cloaking based on Fabry-Perot resonances in single-layer high-index dielectric shells 

      Serebryannikov, A.E.; Usik P.V.; Özbay, Ekmel (Optical Society of American (OSA), 2009)
      Strong reduction of the scattering cross section is obtained for subwavelength dielectric and conducting cylinders without any magnetism for both TE and TM polarizations. The suggested approach is based on the use of ...
    • 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 ...
