A new design of left-handed (LH) metamaterial (MTM) for waveguide applications is presented. The proposed structure is based on two identical circular ring resonators (CRRs) connected with a wire strip (WS). Simulation results show that the planar MTM has a LH resonance at around 10 GHz. Surface current and magnetic field distributions at the resonance are also examined to shown the LH behavior of the structure. In addition, a parametric study based on the gap size of the structure is also given in order to present the dependency of the LH resonance. The results reveals the non-linear relation between the LH resonance and structure dimensions. The parametric study will help us designing more advanced LH MTMs for different waveguide applications.

A New Multi-ring SRR Type Metamaterial Design with Multiple Magnetic Resonances Turkmen, O.; Ekmekci, E.; Sayan, Gönül (2011-03-23) In this study, we propose a new SRR unit cell design for multi-band metamaterial applications. The suggested unit cell structure consists of N number of concentric split rings to obtain magnetic resonances at N distinct frequencies. The value of each distinct resonance frequency can be adjusted by changing design parameters such as metal widths and gap distances for each ring as well as ring-to-ring separations. The suggested multi-band structure is simulated using CST Microwave Studio. Effective medium par...
A Novel Dual-band Metamaterial Structure Ekmekci, E.; Turban-Sayan, G. (2009-08-21) In this study, we propose a novel metamaterial structure having magnetic resonances at two different frequencies and hence providing negative effective permeability values over two separate bandwidths. The introduced metamaterial unit cell topology in this paper is made of a single loop of conducting strip printed over a dielectric substrate with a special winding geometry. Transmission and reflection spectra of this unit cell are simulated using the Ansoft's HFSS software to observe its resonance frequenci...
Alternative design of left-handed metamaterial based on circular resonator and wire strip for waveguide configurations with sensing and absorber applications Gunduz, Ozan T.; Sabah, Cumali (2015-08-01) 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 s...
AN INTERFERENCE AND BEAM SQUINT AWARE HYBRID MASSIVE MIMO FOR SPATIAL WIDEBAND BDMA CHANNELS Özen, Hakan; Güvensen, Gökhan Muzaffer; Department of Electrical and Electronics Engineering (2022-2-10) This study investigates interference and beam squint aware analog beamformer design for massive multiple-input multiple-output (MIMO) systems for spatial wideband beam division multiple access (BDMA) channels. Single carrier frequency domain equalization (SC-FDE) is employed in uplink frequency selective channels. We first design interference and beam squint aware (BSA) narrowband generalized eigenbeamformer (BSA NB GEB) based on a phase shifter (PS) network using slowly varying long-term channel statistics...
A Capacitive MEMS Accelerometer Readout with Concurrent Detection and Feedback Using Discrete Components Terzioglu, Yunus; Alper, Said Emre; Azgın, Kıvanç; Akın, Tayfun (2014-05-08) This paper presents an analog readout method for capacitive MEMS accelerometers in which the feedback actuation and capacitive detection are achieved simultaneously on the same electrode set. The presented circuit operates in closed-loop for improved linearity, and it is constructed in a hybrid platform package in which off-the-shelf discrete components are used together with the silicon-on-glass micro-accelerometer. The system is developed as a practical solution to reduce the complexity of the readout cir...
