Microfluidic sensor applications by using chiral metamaterial
Dalgaç, Şekip; Bakır, Mehmet; Karadağ, Faruk; Karaaslan, Muharrem; Akgöl, Oğuzhan; Ünal, Emin; Sabah, Cumali (World Scientific Publishing Company, 2020)Chiral metamaterial-based sensor is designed for sensing the change in substance ratio of chemical substances when combined with distilled water. These samples have been prepared with 10%, 50% and 90% volume fraction of ... -
Microwave Imager Design with 2.46 GHz Microstrip Patch Antennas
Alkurt, Fatih Özkan; Karaaslan, Muharrem; Ünal, Emin; Karadağ, Faruk (Adıyaman Üniversitesi Fen Bilimleri Dergisi, 2019)In this study, microwave imager design is aimed by using a series of microstrip patch antennas operating in the 2.46 GHz frequency band. The designed microwave imager has a 24-sided cylindrical shape and includes 5x1 ... -
Microwave power imaging detector based on metamaterial absorber
Alkurt, Fatih Özkan; Altıntaş, Olcay; Bakır, Mehmet; Karaaslan, Muharrem; Ünal, Emin; Karadağ, Faruk; Akgöl, Oğuzhan; Sabah, Cumali (SPIE, 2020)Our paper presents the design, fabrication, and characterization of metamaterial absorber-based microwave imaging detector that is operating in industrial, scientific, and medical (ISM) band. The results reveal that the ... -
Negative Refraction in Plasma and Magnetic Materials
Gasimov, Naghi; Karadağ, Faruk; Karaaslan, Muharrem; Veselago, Victor (Institute of Electrical and Electronics Engineers, 2018)The possibility of negative refractive index in plasma and magnetic materials was considered with a new approach. It is shown that simplification of fundamental equations by neglecting losses leads to losing important ... -
Octagonal Shaped Metamaterial Absorber Based Energy Harvester
Alkurt, Fatih Özkan; Altıntaş, Olcay; Bakır, Mehmet; Tamer, Ahmet; Karadağ, Faruk; Bağmancı, Mehmet; Karaaslan, Muharrem; Ünal, Emin; Akgöl, Oğuzhan (Kaunas University of Technology, 2018)In this study, a novel octagonal shaped metamaterial based broadband absorber is proposed for energy harvesting at WIMAX wireless communication band. The proposal has an absorption of 99.97 % at 5.5 GHz with a bandwidth ... -
Some aspects of mass-energy equivalence which appears in left-handed metamaterials
Gasimov, Naghi; Karaaslan, Muharrem; Sabah, Cumali; Karadağ, Faruk (EDP Sciences, 2019)In this work, the concept of mass-energy equivalence in left-handed metamaterials is discussed by following Einstein's box thought experiment. Left-handed metamaterials are artificial composite structures that exhibit ... -
