    • Near-field light localization using subwavelength apertures incorporated with metamaterials 

      Ates, D.; Cakmak, A. O.; Özbay, Ekmel (Elsevier, 2012-03-12)
      We report strong near-field electromagnetic localization by using subwavelength apertures and metamaterials that operate at microwave frequencies. We designed split ring resonators with distinct configurations in order to ...
    • Novel optical antenna designs of comb shaped split ring architecture for NIR and MIR enhanced field localization 

      Kılıç, Veli Tayfun; Ertürk, Vakur B.; Demir, Hilmi Volkan (IEEE, 2014)
      We demonstrated NIR/MIR resonance behavior in optical antennas of comb-shaped split-ring resonators enabling substantially larger field enhancements than single/array of dipoles with the same side length, despite their ...
    • Semiconductor-less photovoltaic device 

      Atar, Fatih B.; Battal, Enes; Aygun, Levent E.; Dağlar, Bihter; Bayındır, Mehmet; Okyay, Ali K. (IEEE, 2013)
      We demonstrate a novel semiconductor-less photovoltaic device and investigate the plasmonic effects on this device structure. The device is made of metal and dielectric layers and the operation is based on hot carrier ...
    • Volumetric plasmonic resonator architecture for thin-film solar cells 

      Sefunc, M.A.; Okyay, A., K.; Demir, Hilmi Volkan (AIP Publishing, 2011-03-04)
      We propose and demonstrate a design concept of volumetric plasmonic resonators that relies on the idea of incorporating coupled layers of plasmonic structures embedded into a solar cell in enhanced optical absorption for ...
