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 ...

Bandwidth Improvement in Bow-Tie Microstrip Antennas: The Effect of Substrate Type and Design Dimensions

Awl, Halgurd N.; Abdulkarim, Yadgar I.; Deng, Lianwen; Bakır, Mehmet; Muhammadsharif, Fahmi F.; Karaaslan, Muharrem; Ünal, Emin; Luo, Heng (Mdpi, 2020)

In this work, the impact of substrate type and design dimensions on bow-tie microstrip antenna performance and bandwidth improvement is presented both numerically and experimentally at 4-8 GHz. The finite integration ...

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)
