    • An electromagnetic sensing system incorporating multiple probes and single antenna for wireless structural health monitoring 

      Özbey, Burak; Altıntaş, Ayhan; Demir, Hilmi Volkan; Ertürk, Vakur B.; Kurç, Ö. (IEEE, 2017)
      In this study, a wireless and passive displacement/strain sensing system is proposed for structural health monitoring (SHM). The wireless and passive interrogation of the sensing unit [a variant of a nested split-ring ...

    • Flexible metamaterials for wireless strain sensing 

      Melik, R.; Unal, E.; Perkgoz, N. K.; Puttlitz, C.; Demir, Hilmi Volkan (American Institute of Physics, 2009-11-04)
      We proposed and demonstrated flexible metamaterial-based wireless strain sensors that include arrays of split ring resonators (SRRs) to telemetrically measure strain. For these metamaterial sensors, we showed that a flexible ...

    • Metamaterial-based wireless strain sensors 

      Melik, R.; Unal, E.; Perkgoz, N. K.; Puttlitz, C.; Demir, Hilmi Volkan (American Institute of Physics, 2009-07-07)
      We proposed and demonstrated metamaterial-based strain sensors that are highly sensitive to mechanical deformation. Their resonance frequency shift is correlated with the surface strain of our test material and the strain ...

    • 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 ...

    • Wavelength tuning of the spirally drawn whispering gallery mode microfiber lasers and the perspectives for sensing applications 

      Yang, Shancheng; Eugene, Tay Yong Kang; Wang, Yue; Zhao, Xin; Demir, Hilmi Volkan; Sun, Handong (OSA - The Optical Society, 2017)
      Facile and cost-efficient microcavities, as well as the tuning of the optical modes, especially for the application of top-grade optical devices, have been emerging as attractive research fields. In this work, controllable ...

    • Wireless sensing in complex electromagnetic media: construction materials and structural monitoring 

      Özbey, B.; Demir, Hilmi Volkan; Kurc, O.; Ertürk, V. B.; Altıntaş, A. (Institute of Electrical and Electronics Engineers Inc., 2015)
      In this paper, wireless sensing in the presence of complex electromagnetic media created by combinations of reinforcing bars and concrete is investigated. The wireless displacement sensing system, primarily designed for ...
