    • Designing materials with desired electromagnetic properties 

      Bulu, I.; Cağlayan, H.; Özbay, Ekmel (Wiley, 2006)
      In this work, we suggest and demonstrate a robust method to tune the plasma frequencies of wire mediums. The method we suggest involves the use of two or more wire arrangements in the unit cell. By incorporating the method ...

    • Electrically controllable plasmon induced reflectance in hybrid metamaterials 

      Habib, Mohsin; Gökbayrak, Murat; Özbay, Ekmel; Cağlayan, H. (American Institute of Physics, 2018)
      The tunable plasmon induced reflectance (PIR) effect has been numerically investigated and experimentally realized by hybrid metal-graphene metamaterials. The PIR effect is produced by two parallel strips of gold (Au) and ...

    • Electrically switchable metadevices via graphene 

      Balcı, Osman; Kakenov, Nurbek; Karademir, E.; Balcı, S.; Çakmakyapan, S.; Polat, E. O.; Cağlayan, H.; Özbay, Ekmel; Kocabaş, Coşkun (American Association for the Advancement of Science, 2018)
      Metamaterials bring subwavelength resonating structures together to overcome the limitations of conventional materials. The realization of active metadevices has been an outstanding challenge that requires electrically ...

    • Experimental demonstration of subwavelength focusing of electromagnetic waves by labyrinth-based two-dimensional metamaterials 

      Bulu, İ.; Cağlayan, H.; Özbay, Ekmel (Optical Society of America, 2006-03-15)
      We studied focusing in a two-dimensional metamaterial that was based on a labyrinth structure. We theoretically showed that the labyrinth-based metamaterial exhibits negative indices of refraction between 6 and 6.4 GlIz. ...

    • Plasmonic structures with extraordinary transmission and highly directional beaming properties 

      Cağlayan, H.; Bulu, I.; Özbay, Ekmel (Wiley Periodicals, 2006)
      We studied the grating-coupling phenomena between surface plasmons and electromagnetic waves in the microwave spectrum. We first present the experimental and theoretical results of an enhanced microwave transmission though ...
