    • Grating based plasmonic band gap cavities 

      Şenlik, S. Seçkin; Kocabaş, Aşkın; Aydınlı, Atilla (Optical Society of American (OSA), 2009-08)
      We report on a comparative study of grating based plasmonic band gap cavities. Numerically, we calculate the quality factors of the cavities based on three types of grating surfaces; uniform, biharmonic and Moiré surfaces. ...
    • Slowing down surface plasmons on a Moiré surface 

      Kocabaş, Aşkın; Şenlik, S. Seçkin; Aydınlı, Atilla (The American Physical Society, 2009-02)
      We have demonstrated slow propagation of surface plasmons on metallic Moiré surfaces. The phase shift at the node of the Moiré surface localizes the propagating surface plasmons and adjacent nodes form weakly coupled ...
