    • All-chalcogenide variable infrared filter 

      Kondakci H.E.; Koylu O.; Yaman, M.; Dana, A.; Bayindir, M. (2009)
      We present the design, fabrication, characterization of spatially variable infrared filter and a demonstration of the filter as a simple infrared spectrometer. A varying photonic band gap filter which consists of thermally ...
    • Compound Hertzian chain model for copper-carbon nanocomposites' absorption spectrum 

      Kokabi, A.; Hosseini, M.; Saeedi, S.; Moftakharzadeh, A.; Vesaghi, M.A.; Fardmanesh, M. (2011)
      The infrared range optical absorption mechanism of carbon-copper composite thin layer coated on the diamond-like carbon buffer layer has been investigated. By consideration of weak interactions between copper nanoparticles ...
    • Experimental verification of metamaterial based subwavelength microwave absorbers 

      Alici, K. B.; Bilotti, F.; Vegni, L.; Ozbay, E. (American Institute of Physics, 2010-10-29)
      We designed, implemented, and experimentally characterized electrically thin microwave absorbers by using the metamaterial concept. The absorbers consist of (i) a metal back plate and an artificial magnetic material layer; ...
    • Photonic metamaterial absorber designs for infrared solar-cell applications 

      Alici, K.B.; Ozbay, E. (2010)
      We propose a metamaterial based absorber design that operates at the infrared regime. The absorption peak was 83.6%. We can incorporate solar-cell layers inside the metamaterial absorber in order to significantly increase ...
