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 ... -
Low-Cost Antenna-Array-Based Metamaterials for Non-Invasive Early-Stage Breast Tumor Detection in the Human Body
Hamza, Musa N.; Abdulkarim, Yadgar I.; Saeed, Salah Raza; Altıntaş, Olcay; Mahmud, Rashad H.; Appasani, Bhargav; Ravariu, Cristian (MDPI, 2022)Microstrip patch antennas have been used in many applications since their appearance. Despite their great promise, their narrow bandwidth and the loss at high-frequency bands have limited their usage in medical applications. ... -
A polarization-insensitive triple-band perfect metamaterial absorber incorporating ZnSe for terahertz sensing
Abdulkarim, Yadgar I.; Alkurt, Fatih Özkan; Bakır, Mehmet; Awl, Halgurd N.; Muhammadsharif, Fahmi F.; Karaaslan, Muharrem; Appasani, Bhargav; Al-Badri, Khalid Saeed Lateef; Zhu, Yuanyuan; Dong, Jian (Institute of Physics, 2022)In this work, a triple-band polarization-insensitive metamaterial structure with perfect absorption is proposed by incorporating a zinc selenide (ZnSe) spacer. The structure was optimally designed by varying the type of ... -
