Determination of frying sunflower oil usage time for local potato samples by using microwave transmission line based sensors

Erdoğan, Maide; Ünal, Emin; Alkurt, Fatih Özkan; Abdulkarim, Yadgar, I.; Deng, Lianwen; Karaaslan, Muharrem (Elsevier, 2020)

Amount of oil usage time can be determined by microwave measurements instead of using complex laboratory equipments to measure oil parameters such as viscosity, base number, refractive index, acid numbers, density, water ...

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 ...

Enhancement of image quality by using metamaterial inspired energy harvester

Alkurt, Fatih Özkan; Altıntaş, Olcay; Özaktürk, Melikşah; Karaaslan, Muharrem; Akgöl, Oğuzhan; Ünal, Emin; Sabah, Cumali (Elsevier, 2020)

Metamaterial energy harvester based subwavelength imaging structure is presented. Besides, 2x2 array patch antenna is designed to create incident radiated signal towards the proposed harvester structure. Harvested energy ...

Investigation of microwave power limiter for Industrial Scientific Medical band (ISM) applications

Sardi, Azzeddine; Alkurt, Fatih Özkan; Özkaner, Vedat; Karaaslan, Muharrem; Ünal, Emin; Mohamed, Taouzari (Wiley, 2020)

In this paper, a new design of microstrip power limiter which is based on microstrip technology and zero bias Schottky diode is introduced. In this context, the FR-4 substrate that was characterized by dielectric permittivity ...
