An alternative design of left-handed (LH) metamaterial (MTM) for waveguide configurations is presented with sensor and absorber applications. The LH structure is based on two identical circular ring resonators connected with a wire strip. Both simulation and experimental results show that the planar MTM has an LH resonance at similar to 9.9 GHz. Surface current and magnetic field distributions at the resonance are also presented to show the LH behavior of the structure in detail. In addition, a parametric study based on the gap size of the structure is also provided in order to present the dependency of the LH resonance. Next, the sensing process is presented with respect to the thickness, position, and dielectric constant variations of the superstrate layer located in front of the material surface. Finally, the absorption application of the structure in X-band is shown, and the results show that the absorber behaves as a perfect absorber with an absorption rate of 99.99%. As a result, the proposed structure can be used in many MTM applications, such as sensor, absorber, and soon. (C) 2015 Society of Photo-Optical Instrumentation Engineers (SPIE)

Integrated optical modulators with zero index metamaterials based on photonic crystal slab waveguides Yildirim, Mustafa; GÖVDELİ, ALPEREN; Kocaman, Serdar (2019-01-01) A novel integrated optical modulator design is presented using zero index metamaterial-based Mach-Zehnder Interferometer with photonic crystal phase shifters. The phase modulation relies on the shift between the photonic bandgaps having non-zero and zero effective refractive indices. A small change in the bulk index results in an effective index change between the arms of the MZI due to the disturbance of the band structure. Thus, such a structure provides a new approach for phase modulation on integrated o...
Adaptive Nonlinear Control Combined With Unscented Kalman Filter for Permanent Magnet Synchronous Motor Fed by AC/DC/AC Converter Titaouine, A.; Taibi, D.; Bennis, O.; Benchabane, F.; Boumaraf, R.; Yahia, K. (2011-09-10) In this paper, a adaptive non-linear controller is presented for permanent magnet synchronous motor (PMSM) sensorless drives. The adaptive non-linear controller is designed based on an input-output feedback linearization control technique. The unscented Kalman filter is used to estimate the speed, position and load torque. The PMSM is fed by an indirect power electronics converter. This indirect converter is controlled by a sliding mode technique that enables minimization of harmonics introduced by the line...
Implementation of a perfect metamaterial absorber into multi-functional sensor applications AKGÖL, OĞUZHAN; KARAASLAN, MUHARREM; ÜNAL, EMİN; Sabah, C. (2017-05-30) Perfect metamaterial absorber (MA)-based sensor applications are presented and investigated tigated in the microwave frequency range. It is also experimentally analyzed and tested to verify the behavior of the MA. Suggested perfect MA -based sensor has a simple configuration which introduces flexibility to sense the dielectric properties of a material and the pressure of the medium. The investigated applications include pressure and density sensing. Besides, numerical simulations verify that the suggested s...
Experimental evaluation of cable drum systems as linear motion sensors KILIÇ, ERGİN; Dölen, Melik; Koku, Ahmet Buğra (2011-04-15) This study evaluates cable-drum mechanisms as linear motion sensors for certain CNC applications. In this work, the dynamical attributes of a generic device are studied experimentally. The conducted research indicates that despite the significant traction force induced between the cable and its drum, small fluctuations in mechanism's speed yields a considerable (micro) slip at the interface.
Design optimization of a fully integrated charge-pump with LC tank oscillator for ultra-low voltage energy harvesting Jayaweera, H. M. P. C.; Muhtaroglu, Ali (2017-01-01) Model based optimization of a novel integrated interface circuit topology is presented for low voltage DC-DC step-up conversion. A cross-coupled charge pump is implemented in standard 0.18 mu m CMOS technology using an integrated LC tank oscillator to enable a compact, low cost, self-starting solution with maximum efficiency at ultra-low input voltage levels available from embedded micro-power generators. The voltage doubling oscillator can start up with input as low as 0.10 V. Full system can step 0.2 V up...
