Microfluidic Reconfigurable Nested Split Ring-Regular Ring Transmitarray Unit Cell Erdil, Emre; Topalli, Kagan; Esmaeilzad, Nasim Seyedpour; Zorlu, Ozge; Külah, Haluk; Aydın Çivi, Hatice Özlem (2014-08-23) A reconfigurable, circularly polarized transmitarray unit cell consisting of double layer nested split ring-regular ring formed as microfluidic channels inside Polydimethylsiloxane (PDMS) is designed and fabricated. The operation of the unit cell is based on the element rotation method. The liquid metal is injected into the channels and it forms the conductive part in the structures whereas the split region in the outer ring is air. The movement of the liquid metal together with the split around the outer r...
Interband optical absorption obtained by pseudopotential method for type-II InAs/GaSb SL photodetectors Akel, Kazim; Hoştut, Mustafa ; Akın, Tayfun; Ergun, Yuksel (2021-05-01) We have calculated interband optical absorption for InAs/GaSb based type-II superlattice (SL) structures. The empirical pseudopotential method (EPM) has been used as an alternative to the k.p method since it is less sophisticated while providing similar results in the mid wavelength infrared range and long wavelength infrared range atmospherics bands for comparison. EPM results show that the bandgap wavelengths of SLs have been predicted with the underestimating of 0.4 mu m. This corresponds to an uncertain...
Current injection optimization for magnetic resonance-electrical impedance tomography (MREIT) Altunel, H.; Eyüboğlu, Behçet Murat; KÖKSAL, ADNAN (2007-09-02) Determining optimum current injection pattern is of interest in magnetic resonance-electrical impedance tomography (MREIT), since it helps in detecting smaller inhomogeneities within the body when total injected current into the body is limited. Based on this fact, for 2-D cylindrical body with concentric and cylindrical inhomogeneity, current injection optimization problem is analytically formulated, based on distinguishability definition for MREIT. The exterior penalty method is used to solve the optimiza...
INVIVO IMAGING OF CARDIAC RELATED IMPEDANCE CHANGES Eyüboğlu, Behçet Murat; BARBER, DC (1989-03-01) Electrical impedance tomography (EIT) produces cross-sectional images of the electrical resistivity distribution within the body, made from voltage or current measurements through electrodes attached around the body. The authors describe a gated EIT system to image the cardiogenic electrical resistivity variations and the results of in vivo studies on human subjects. It is shown that the sensitivity of EIT to tissue resistivity variations due to blood perfusion is good enough to image blood flow to the lung...
Spatial stabilization of Townsend and glow discharges with a semiconducting cathode Salamov, BG; Ellialtioglu, S; Akınoğlu, Bülent Gültekin; Lebedeva, NN; Patriskii, LG (IOP Publishing, 1996-03-14) The physical processes determining the functions of an ionization system and especially the discharge stabilization by the distributed resistance of a semiconducting cathode in such a system are studied. The current-voltage (I-U) characteristics of the system with a semiconducting GaAs cathode are obtained experimentally as functions of the gap pressure P (16-760 Torr) and inter-electrode distance d (10 mu m to 5 mm), which are varied for the first time over very wide ranges. The experiments showed that the...
