    • Digital microfluidics for reconfigurable antennas 

      Damgaci, Y.; Çağatay, Engin; Bıyıklı, Necmi; Cetiner, B. A. (IEEE, 2014)
      Usage of fluids (microfluidic or otherwise) in antennas provides a conceptually easy reconfiguration mechanism in the aspect of physical alteration. However, a requirement of pumps, valves, etc. for liquid transportation ...

    • Fabrication and characterization of liquid metal-based micro-electromechanical DC-contact switch for RF applications 

      Çağatay, Engin; Noyan, Mehmet Alican; Damgaci, Y.; Cetiner, B. A.; Bıyıklı, Necmi (CRC Press, 2012)
      We demonstrate that room-temperature liquid metal alloy droplets of Eutectic Gallium Indium (EGaIn) and Gallium Indium Tin alloy (Galinstan) can be actuated using electro-wetting-on-dielectric (EWOD) effect. With the ...

    • Low-voltage small-size double-arm MEMS actuator 

      Bıyıklı, Necmi; Damgaci, Y.; Cetiner, B.A. (2009)
      The fabrication and characterisation of a double-arm cantilever-type metallic DC-contact MEMS actuator with low pull-down voltage are reported. Bi-layer TiW cantilevers with an internal stress gradient were fabricated using ...

    • Nanoelectromechanical switches for reconfigurable antennas 

      Cetiner, B.A.; Bıyıklı, Necmi; Yildirim, B.S.; Damgaci, Y. (2010)
      We report on the full-wave analyses of a frequency reconfigurable antenna integrated with metallic nanoelectromechanical system (NEMS) switches (length = 3 μm, width = 60 nm). The NEMS switch used in this work has the same ...
