    • 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 ...

    • Graphene-enabled electrically switchable radar-absorbing surfaces 

      Balci O.; Polat, E.O.; Kakenov, N.; Kocabas, C. (Nature Publishing Group, 2015)
      Radar-absorbing materials are used in stealth technologies for concealment of an object from radar detection. Resistive and/or magnetic composite materials are used to reduce the backscattered microwave signals. Inability ...

    • Surface plasmon based enhanced transmission of electromagnetic waves 

      Bıyıklı, Süheyla Sena Akarca (Bilkent University, 2004)
      Grating-coupling phenomena between surface plasmons and electromagnetic waves are studied in the microwave spectrum using metallic gratings. Transmission and reflection measurements were carried out to observe the transmitted ...

    • Transmission enhancement through deep subwavelength apertures using connected split ring resonators 

      Ates, D.; Cakmak, A.O.; Colak, E.; Zhao, R.; Soukoulis, C.M.; Özbay, Ekmel (Optical Society of American (OSA), 2010)
      We report astonishingly high transmission enhancement factors through a subwavelength aperture at microwave frequencies by placing connected split ring resonators in the vicinity of the aperture. We carried out numerical ...
