In this paper, the development of an all 3-D printed wide band (2-18 GHz) free-space measurement system for characterizing the complex dielectric properties of flexible as well as rigid materials was demonstrated. Each part of the setup was designed and simulated precisely to show the effect of the 3-D printed quasi-optical lenses placed in front of the wide band ridged horn antennas on the beam and radiation pattern. More than 10 parts of the setup were 3-D printed using two different 3-D printers, and the parts were assembled together with precise alignment. The method used to analytically extract the dielectric properties was explained in detail, and the analytical S-parameters were compared with experimental S-parameters for various plastic materials to verify the measurement system. Four types of commercially available materials: polyimide film (Kapton), liquid crystalline polymer sheet (LCP), ceramic-filled polytetrafluoroethylene composites (R03035), and polypropylene with different thicknesses were characterized, and obtained dielectric constant and loss tangent values were compared with the data available from the vendors.

An optical fiber radiation sensor for remote detection of radiological materials Klein, DM; Yukihara, EG; Bulur, Enver; Durham, JS; Akselrod, MS; McKeever, SWS (Institute of Electrical and Electronics Engineers (IEEE), 2005-08-01) This paper demonstrates the feasibility of a portable radiation sensor system that uses the pulsed optically stimulated luminescence technique to remotely interrogate an aluminum oxide (Al2O3:C) radiation sensor via an optical fiber. The objective is to develop a system for applications requiring simple and inexpensive sensors for widespread monitoring of ionizing radiation levels, which can be remotely interrogated at regular periods with little or no human intervention and are easy to install, operate, an...
Metamaterial absorber-based sensor embedded into X-band waveguide SABAH, CUMALİ; TURKMEN-KUCUKSARİ, OZNUR; Sayan, Gönül (Institution of Engineering and Technology (IET), 2014-07-17) A novel metamaterial sensor, integrated with an X-band waveguide, is proposed for high-resolution measurements of variations in the dielectric constant and/or the thickness of a superstrate layer that covers a pair of absorber unit cells. Variations in superstrate parameters are potentially caused by physical, chemical or biological factors, and can be detected by measuring the corresponding shifts in the resonance frequency of the metamaterial sensor. It is estimated by simulation results that resolution l...
A Dual-Resonator Temperature Sensing Approach With Time Base Error Suppression Kaya, Onurcan; Azgın, Kıvanç (Institute of Electrical and Electronics Engineers (IEEE), 2020-01-15) In this study we present a novel dual-resonator temperature sensor which can be embedded in other MEMS sensors for improved thermal compensation and on-the-run calibration. For accurate temperature measurements, the proposed method mitigates time base errors in frequency counting, eliminates the need for a highly accurate reference clock and can cancel out the effects of aging of the time base without using a calibration process. The sensor structure is composed of a strain amplifying beam and two Double En...
Pirani Vacuum Gauges Using Silicon-on-Glass and Dissolved-Wafer Processes for the Characterization of MEMS Vacuum Packaging Topalli, Ebru Sagiroglu; Topalli, Kagan; Alper, Said Emre; Serin, Tulay; Akın, Tayfun (Institute of Electrical and Electronics Engineers (IEEE), 2009-03-01) This paper presents the design and implementation of Pirani vacuum gauges for the characterization of vacuum packaging of microelectromechanical systems (MEMS). Various Pirani vacuum gauges are fabricated with two different standard in-house fabrication processes, namely the silicon-on-glass (SOG) process and dissolved-wafer process (DWP). The Pirani gauges utilize meander-shaped suspended silicon coils as the heaters and two isolated silicon islands in the close proximity of the heater that function as dua...
An on-die ultra-low voltage DC-DC step-up converter with voltage doubling LC-tank Jayaweera, H. M. P. C.; Pathirana, W. P. M. R.; Muhtaroglu, Ali (IOP Publishing; 2016-12-01) In this paper we report the design, characterization and verification of a novel on-die ultra-low voltage DC-DC converter circuit for energy harvester applications in 0.18 mu m complementary metal oxide semiconductor (CMOS) technology. The circuit self-starts, does not use off-chip components, and is thus suitable for use in highly integrated low cost systems. The first version of the design has a five-stage charge-pump stimulated by an oscillator with two center-tap inductors. It is validated on a test chi...
