    • Experimental observation of cavity formation in composite metamaterials 

      Caglayan H.; Bulu I.; Loncar, M.; Özbay, Ekmel (Optical Society of American (OSA), 2008)
      In this paper, we investigated one of the promising applications of left-handed metamaterials: composite metamaterial based cavities. Four different cavity structures operating in the microwave regime were constructed, and ...

    • Experimental observation of true left-handed transmission, negative refraction and negative phase velocity in composite metamaterials 

      Özbay, Ekmel; Soukoulis, C. M. (IEEE, 2005)
      We report a true left-handed (LH) behavior in a composite metamaterial consisting of periodically arranged split ring resonator (SRR) and wire structures. The magnetic resonance of the SRR structure is demonstrated by ...

    • Nested metamaterials for wireless strain sensing 

      Melik, R.; Unal, E.; Perkgoz, N. K.; Santoni, B.; Kamstock, D.; Puttlitz, C.; Demir, Hilmi Volkan (IEEE, 2009-12-28)
      We designed, fabricated, and characterized metamaterial-based RF-microelectromechanical system (RF-MEMS) strain sensors that incorporate multiple split ring resonators (SRRs) in a compact nested architecture to measure ...

    • Observation of defect formation in metamaterials 

      Çağlayan, Hümeyra; Bulu, I.; Loncar, M.; Özbay, Ekmel (OSA, 2008-10)
      We report subwavelength localization of electromagnetic fields within cavities based on metamaterials. Cavity resonances are observed in the transmission spectrum of a split ring resonator and composite metamaterials cavity ...

    • Spectral scalability and optical spectra of fractal multilayer structures: FDTD analysis 

      Şimsek, Şevket; Palaz, Selami; Mamedov, Amirullah M.; Özbay, Ekmel (Springer Verlag, 2017)
      An investigation of the optical properties and band structures for the conventional and Fibonacci photonic crystals (PCs) based on SrTiO3 and Sb2Te3 is made in the present research. Here, we use one-dimensional SrTiO3- and ...

    • Two-dimensional ferroelectric photonic crystals: Optics and band structure 

      Simsek S.; Mamedov, A. M.; Özbay, Ekmel (Taylor & Francis Inc., 2013-09-20)
      In this report we present an investigation of the optical properties and band structure calculations for the photonic structures based on the functional materials- ferroelectrics. A theoretical approach to the optical ...
