Wideband metamaterial absorber based on CRRs with lumped elements for microwave energy harvesting

Bağmancı, Mehmet; Karaaslan, Muharrem; Altıntaş, Olcay; Karadağ, Faruk; Tetik, Erkan; Bakır, Mehmet (Taylor & Francis, 2018)

A novel metamaterial absorber structure is designed and characterized for microwave energy harvesting. The suggested structure is composed of two circular ring resonators with different dimensions. Due to harvesting ...

Tunable energy harvesting on UHF bands especially for GSM frequencies

Bakır, Mehmet; Karaaslan, Muharrem; Altıntaş, Olcay; Bağmancı, Mehmet; Akdoğan, Volkan; Temurtaş, Feyzullah (Cambridge University Press, 2018)

Metamaterial-based energy harvesting structures operating at GSM goo and GSM 1800 frequency bands have been proposed. The basic structure is composed of four nested U-shaped elements on the front and back side of the ...

Sensory applications of resonator based metamaterial absorber

Bakır, Mehmet; Karaaslan, Muharrem; Akgöl, Oğuzhan; Altıntaş, Olcay; Ünal, Emin; Sabah, Cumali (Elsevier GmbH, 2018)

Metamaterials are attractive media for scientific society for their potential multi-functional and a wide range of applications due to their unusual electromagnetic properties. In this paper, we present several important ...

A Symmetrical Terahertz Triple-Band Metamaterial Absorber Using a Four-Capacitance Loaded Complementary Circular Split Ring Resonator and an Ultra-Thin ZnSe Substrate

Abdulkarim, Yadgar, I.; Alkurt, Fatih Özkan; Awl, Halgurd N.; Altıntaş, Olcay; Muhammadsharif, Fahmi F.; Appasani, Bhargav; Bakır, Mehmet; Karaaslan, Muharrem; Taouzari, Mohamed; Dong, Jian (MDPI, 2022)

In this research work, a symmetrical four-capacitance loaded complementary circular split ring resonator is proposed, which uses an ultra-thin Zinc Selenide (ZnSe) substrate to realize a low-profile triple-band metamaterial ...

Enhanced Sensing Capacity of Terahertz Triple-Band Metamaterials Absorber Based on Pythagorean Fractal Geometry

Mazare, Alin Gheorghita; Abdulkarim, Yadgar I.; Karim, Ayoub Sabir; Bakır, Mehmet; Taouzari, Mohamed; Muhammadsharif, Fahmi F.; Appasani, Bhargav; Altıntaş, Olcay; Karaaslan, Muharrem; Bizon, Nicu (MDPI, 2022)

A new design of a triple band perfect metamaterial absorber based on Pythagorean fractal geometry is proposed and analyzed for terahertz sensing applications. The proposed design showed an enhanced sensing performance and ...
