    • Design and fabrication of micromachined radio-frequency cavity resonators 

      Arslan, Cihan Hakan (Bilkent University, 2006)
      Resonators are used almost in every wireless communications applications and play an important role in the performance of these systems. At radio frequencies, for high performance applications, realization of high-Q ...

    • Metamaterial-based wireless RF-MEMS strain sensors 

      Melik, Rohat; Ünal, Emre; Perkgoz, Nihan Kosku; Puttlitz, C.; Demir, Hilmi Volkan (IEEE, 2010)
      Approximately 10% of the fractures do not heal properly because of the inability to monitor fracture healing. Standard radiography is not capable of discriminating whether bone healing is occurring normally or aberrantly. ...

    • 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 ...

    • Novel wireless RF-bioMEMS implant sensors of metamaterials 

      Melik, Rohat (Bilkent University, 2010)
      Today approximately one out of ten patients with a major bone fracture does not heal properly because of the inability to monitor fracture healing. Standard radiography is not capable of discriminating whether bone healing ...

    • RF-MEMS load sensors with enhanced Q-factor and sensitivity in a suspended architecture 

      Melik, R.; Unal, E.; Perkgoz, N. K.; Puttlitz, C.; Demir, Hilmi Volkan (Elsevier, 2010-11-09)
      In this paper, we present and demonstrate RF-MEMS load sensors designed and fabricated in a suspended architecture that increases their quality-factor (Q-factor), accompanied with an increased resonance frequency shift ...
