Antenna-based microwave absorber for imaging in the frequencies of 1.8, 2.45, and 5.8 GHz

Alkurt, Fatih Özkan; Altıntaş, Olcay; Atcı, Ahmet; Bakır, Mehmet; Ünal, Emin; Akgöl, Oğuzhan; Delihacıoğlu, Kemal; Karaaslan, Muharrem; Sabah, Cumali (The International Society for Optics and Photonics (SPIE), 2018)

We propose a microwave imaging structure with GSM, ISM, Wi-Fi, and WiMAX operating frequencies at 1.80, 2.45, and 5.80 GHz, respectively. The suggested structure is based on a microwave antenna-inspired absorber with ...

Broad band metamaterial absorber based on wheel resonators with lumped elements for microwave energy harvesting

Karaaslan, Muharrem; Bağmancı, Mehmet; Ünal, Emin; Akgöl, Oğuzhan; Altıntaş, Olcay; Sabah, Cumali (Springer, 2018)

A new metamaterial absorber structure is designed and characterized both numerically and experimentally for microwave energy harvesting applications. The proposed structure includes four wheel resonators with different ...
