We present low-cost fabrications of inkjet-printed metamaterials that are resonating at microwave frequencies. A very low-cost setup involving commercial desktop printers loaded with silver-based inks is constructed and used to fabricate the metamaterials. We show that, despite the challenges in the low-cost fabrication processes, successful prints, and metamaterial samples can be obtained. A composite metamaterial design, which possesses a bandlimited transparency due to the induced negative refractive index, is fabricated and tested to demonstrate the feasibility of low-cost metamaterials with relatively complex geometries involving three-dimensional arrangements.

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...
Investigation of Alternative Array Configurations of Nanowires for Maximum Power Transmission at Optical Frequencies Karaosmanoglu, Bariscan; Satana, Hasan Aykut; Dikmen, Fatih; Ergül, Özgür Salih (2017-07-14) We present a computational analysis and comparison of nanowire arrays for efficient transmission of electromagnetic power at optical frequencies. A reliable simulation environment involving the multilevel fast multipole algorithm for fast iterative solutions of surface integral equations is used to accurately compute field intensity and power density values in the vicinity of nanowires in diverse configurations. The results demonstrate favorable properties of honeycomb structures that can provide efficient ...
Sensitive Metamaterial Sensor for Distinction of Authentic and Inauthentic Fuel Samples Tumkaya, Mehmet Ali; Dincer, Furkan; KARAASLAN, MUHARREM; Sabah, Cumali (2017-08-01) A metamaterial-based sensor has been realized to distinguish authentic and inauthentic fuel samples in the microwave frequency regime. Unlike the many studies in literature on metamaterial-based sensor applications, this study focuses on a compact metamaterial-based sensor operating in the X-band frequency range. Firstly, electromagnetic properties of authentic and inauthentic fuel samples were obtained experimentally in a laboratory environment. Secondly, these experimental results were used to design and ...
Investigation of microwave metamaterial based on H-shaped resonator in a waveguide configuration and its sensor and absorber applications Sabah, Cumali; Taygur, Mehmet Mert; ZORAL, EMİNE YEŞİM (2015-04-13) A microwave metamaterial (MTM) based on H-shaped resonator in a waveguide configuration is introduced and investigated both numerically and experimentally for X-band frequencies. The proposed model is designed and fabricated on both sides of the substrate and exhibits strong magnetic resonance at around 10.5GHz. Additionally, it has very simple design which improves and simplifies the fabrication process. Besides, only one single slab is used in the simulation and experiment which provides a reduction in th...
Improvement of finite element model by using sine vibration test results of acommunication satellite Çekiç, Abdulkadir; Yaman, Yavuz; Department of Aerospace Engineering (2021-2-15) In this thesis, the vibration analysis of a communication satellite is performed,and the improvementof the finite element model by using vibration test results is presented. First, the satellite finite element model isgenerated using MSC/PATRAN and MSC/NASTRAN commercial software. With the natural frequency and frequency response analysis, the expected frequency values and response amplitudes in accelerometers arecalculated in vibration tests.
