    • Beaming and localization of electromagnetic waves in periodic structures 

      Çağlayan, Hümeyra (Bilkent University, 2010)
      We want to manipulate light for several applications: microscopy, data storage, leds, lasers, modulators, sensor and solarcells to make our life healthier, easier or more comfortable. However, especially in small scales ...

    • Characterization and applications of negative-index metamaterials 

      Aydın, Koray (Bilkent University, 2008)
      Metamaterials offer novel electromagnetic properties and promising applications including negative refraction, flat-lenses, superlenses, cloaking devices. In this thesis, we characterized the negative-index metamaterials ...

    • The left hand of electromagnetism : metamaterials 

      Alıcı, Kamil Boratay (Bilkent University, 2010)
      Metamaterials are artificial periodic structures whose electromagnetic response is solely dependent on the constituting unit cells. In the present thesis, we studied unit cell characteristics of metamaterials that has ...
