This paper presents a reconfigurable circularly polarized transmitarray unit cell by microfluidic technology. The unit cell comprises double layer nested ring-split rings formed as microfluidic channels in the Polydimethylsiloxane (PDMS) material using soft lithography techniques. In this structure, only the inner ring has a split region and this region is realized by leaving a gap in the channel filled by an injected liquid metal whereas the outer channel is filled by the liquid metal. Transmission phase of the unit cell is adjusted by implementing rotational phase shifting via manipulating the liquid metal in the channels. X-band unit cell prototypes are fabricated on a glass substrate.

A Reconfigurable Microfluidic Transmitarray Unit Cell Erdil, Emre; Topalli, Kagan; Zorlu, Ozge; Toral, Taylan; YILDIRIM, ENDER; KÜLAH, HALUK; Aydın Çivi, Hatice Özlem (2013-04-12) This paper presents a novel microfluidics based approach to develop a reconfigurable circularly polarized transmitarray unit cell. The unit cell comprises double layer nested split ring slots formed as microfluidic channels that can be filled by fluids. Split regions in the slots are realized by injecting liquid metal into the channels. Beam steering is obtained by implementing rotational phase shifting via manipulating the liquid metal in the slots. X-band unit cell prototypes are fabricated on glass subst...
Design and implementation of reconfigurable transmitarray unit cells employing the element rotation method by microfluidics Erdil, Emre; Aydın Çivi, Hatice Özlem; Topallı, Kağan; Department of Electrical and Electronics Engineering (2014) This thesis presents design, fabrication and measurement of a novel, continuously tunable, circularly polarized X-band microfluidic transmitarray unit cell. To the author’s knowledge, this is the first study in the literature where a microfluidics approach is used to tune the phase of the transmitted field through the unit cell by the element rotation method. Furthermore, the generalized transmitarray design conditions necessary to utilize the element rotation method are derived. To implement the novel micr...
Reconfigurable Nested Ring-Split Ring Transmitarray Unit Cell Employing the Element Rotation Method by Microfluidics Erdil, Emre; TOPALLI, KAĞAN; Esmaeilzad, Nasim S.; Zorlu, Ozge; Külah, Haluk; Aydın Çivi, Hatice Özlem (2015-03-01) A continuously tunable, circularly polarized X-band microfluidic transmitarray unit cell employing the element rotation method is designed and fabricated. The unit cell comprises a double layer nested ringsplit ring structure realized as microfluidic channels embedded in Polydimethylsiloxane (PDMS) using soft lithography techniques. Conductive regions of the rings are formed by injecting a liquid metal (an alloy of Ga, In, and Sn), whereas the split region is air. Movement of the liquid metal together with ...
A dielectrophoretic cell/particle separator fabricated by spiral channels and concentric gold electrodes Yilmaz, G.; Çiftlik, A.T.; Külah, Haluk (2009-12-14) This paper presents the design and implementation of a novel dielectrophoresis (DEP) system with spiral channels and concentric electrodes for high resolution cell separation applications. The device is fabricated with a 4 mask parylene process and the design is optimized in MATLAB Simulink reg to confine the operation. Tests with micro particles of different sizes are performed to show size-based separation by dielectrophoresis. Proposed device is also tested with K562 leukemia cell lines to prove that the...
A 180 nm Self-Powered Rectifier Circuit for Electromagnetic Energy Harvesters Ulusan, Hasan; Zorlu, Ozge; Külah, Haluk; Muhtaroglu, Ali (2013-12-18) This paper presents a new self-powered low voltage rectifier implementation for vibration-based electromagnetic (EM) energy harvesters. The proposed circuit is an improved version of the previously reported rectifier, which was designed in TSMC 90 nm CMOS technology. The circuit is designed in lower cost UMC 180 nm CMOS technology, and uses a passive AC/DC quadrupler structure to supply the external power of the utilized active components. Simulation results show that the maximum power conversion efficiency...
