    • Raman enhancement on a broadband meta-surface 

      Ayas S.; Güner, H.; Türker, B.; Ekiz, O. O.; Dirisaglik, F.; Okyay, A., K.; Dâna, A. (American Chemical Society, 2012-07-30)
      Plasmonic metamaterials allow confinement of light to deep subwavelength dimensions, while allowing for the tailoring of dispersion and electromagnetic mode density to enhance specific photonic properties. Optical resonances ...
    • Rounding corners of nano-square patches for multispectral plasmonic metamaterial absorbers 

      Ayas S.; Bakan, G.; Dana, A. (OSA - The Optical Society, 2015)
      Multispectral metamaterial absorbers based on metal-insulatormetal nano-square patch resonators are studied here. For a geometry consisting of perfectly nano-square patches and vertical sidewalls, double resonances in the ...
