      Hybridization of fano and vibrational resonances in surface-enhanced infrared absorption spectroscopy of streptavidin monolayers on metamaterial substrates 

      Alici, K. B. (2014)
      We present spectral hybridization of organic and inorganic resonant materials and related bio-sensing mechanism. We utilized a bound protein (streptavidin) and a Fano-resonant metasurface to illustrate the concept. The ...

      Chiral metamaterials: From negative index to asymmetric transmission 

      Mutlu, Mehmet; Li, Zhaofeng; Özbay, Ekmel (IEEE, 2013)
      Chiral metamaterials are attractive for their intriguing properties such as negative refractive index, optical activity and circular dichroism, and asymmetric transmission. In this paper, we review the research we have ...

      Radiation properties and coupling analysis of a metamaterial based, dual polarization, dual band, multiple split ring resonator antenna 

      Alici, K. B.; Serebryannikov, A. E.; Özbay, Ekmel (Taylor and Francis, 2012-04-03)
      We demonstrate an electrically small antenna that operates at two modes, which correspond to two orthogonal polarizations. The antenna was single fed and composed of perpendicularly placed metamaterial elements and a ...

      The magical world of metamaterials 

      Çağlayan, Hümeyra; Özbay, Ekmel (SPIE, 2009)
      We review experimental and theoretical studies performed on left-handed metamaterials (LHM). The metamaterials exhibit quiet unusual electromagnetic properties such as negative refraction, negative phase velocity, subwavelength ...

      Photonic metamaterial absorber designs for infrared solar-cell applications 

      Alıcı, Kamil Boratay; Özbay, Ekmel (SPIE, 2010)
      We propose a metamaterial based absorber design that operates at the infrared regime. The absorption peak was 83.6%. We can incorporate solar-cell layers inside the metamaterial absorber in order to significantly increase ...

      Long-range tamm surface plasmons supported by graphene-dielectric metamaterials 

      Hajian, H.; Caglayan, H.; Özbay, Ekmel (American Institute of Physics Inc., 2017)
      Considering the Ohmic losses of graphene in the calculations and by obtaining exact dispersion relations of the modes, we theoretically study propagation and localization characteristics of Tamm surface plasmons supported ...

      Identifying magnetic response of split-ring resonators at microwave frequencies 

      Aydin, K.; Özbay, Ekmel (Sciendo, 2006)
      In this study we provide experimental methods to identify the magnetic resonance of split ring resonators (SRR) at the microwave frequency regime. Transmission measurements were performed on both single SRR unit cell and ...

      Lithography-free planar band-pass reflective color filter using a series connection of cavities 

      Ghobadi, Amir; Hajian, Hodjat; Soydan, Mahmut Can; Bütün, Bayram; Özbay, Ekmel (Nature Publishing Group, 2019-01)
      In this article, a lithography-free multilayer based color flter is realized using a proper series connection of two cavities that shows relatively high efciency, high color purity, and a wide view angle. The proposed ...

      Design of miniaturized narrowband absorbers based on resonant-magnetic inclusions 

      Bilotti, F.; Toscano, A.; Alici, K. B.; Özbay, Ekmel; Vegni, L. (IEEE, 2011-06-21)
      In this paper, we present the design of miniaturized narrowband-microwave absorbers based on different kinds of magnetic inclusions. The operation of the proposed components originates from the resonance of a planar array ...

      Retrieval of effective parameters for bianisotropic metamaterials with omega shaped metallic inclusions 

      Li, Z.; Aydin, K.; Özbay, Ekmel (Elsevier, 2011-11-18)
      Bianisotropic metamaterials including Ω-shaped metallic elements are investigated experimentally and theoretically. A passband is observed for a composite metamaterial (CMM) based on an Ω-medium below the plasmonic frequency ...
