Radiation pattern reconfigurable cubical antenna array for 2.45 GHz wireless communication applications
Alkurt, Fatih Özkan; Ünal, Emin; Palandöken, Merih; Abdulkarim, Yadgar I.; Hasar, Uğur Cem; Karaaslan, Muharrem (Springer, 2022)In this paper a single-fed four-faced multidirectional compact antenna is introduced for 2.45 GHz indoor wireless applications. Firstly, a slotted patch antenna is designed to operate at 2.45 GHz and its equivalent circuit ... -
Simulated and experimental verification of the microwave dual-band metamaterial perfect absorber based on square patch with a 45(0) diagonal slot structure
Al-badri, Khalid Saeed Lateef; Abdulkarim, Yadgar I.; Alkurt, Fatih Özkan; Karaaslan, Muharrem (Taylor and Francis, 2021)In this paper, we designed a dual band metamaterial perfect absorber (MPA) for Ku band applications. The overall ultrathin layer of proposed absorber consists of square patch with 450 diagonal slot structure within a copper ... -
Simulation and lithographic fabrication of a triple band terahertz metamaterial absorber coated on flexible polyethylene terephthalate substrate
Abdulkarim, Yadgar I.; Xiao, Meiyu; Awl, Halgurd N.; Muhammadsharif, Fahmi F.; Lang, Tingting; Saeed, Salah Raza; Alkurt, Fatih Özkan; Bakır, Mehmet; Karaaslan, Muharrem; Dong, Jian (The Optical Society, 2022)A triple band metamaterial absorber in the terahertz range, incorporating a three closed circle ring resonator, was designed and fabricated on flexible polyethylene terephthalate “PET” substrate. The proposed design was ... -
A study on electronically controllable beamforming monopole antenna for telecommunication applications
Alkurt, Fatih Özkan; Ünal, Emin; Palandöken, Merih; Altıntarla, Gizem; Abdulkarim, Yadgar I.; Hasar, Uğur Cem; Karaaslan, Muharrem (Taylor and Francis, 2022)The design, analysis, and prototyping of an electronically controllable beamforming monopole antenna (ECBMA), which could be a good candidate for ceil-mounted wireless telecommunication systems, are reported. The proposed ... -
A thermally stable and polarization insensitive square-shaped water metamaterial with ultra-broadband absorption
Abdulkarim, Yadgar I.; Awl, Halgurd N.; Alkurt, Fatih Özkan; Muhammadsharif, Fahmi F.; Saeed, Salah Raza; Karaaslan, Muharrem; Bakır, Mehmet; Luo, Heng (Elsevier, 2021)In this paper, square-shaped water metamaterial is reported, which can be used as a perfect absorber for ultra-broadband absorption in the microwave frequency range. Computer Simulation Technology (CST) software was used ... -
An ultrathin and dual band metamaterial perfect absorber based on ZnSe for the polarization-independent in terahertz range
Abdulkarim, Yadgar I.; Alkurt, Fatih Özkan; Awl, Halgurd N.; Muhammadsharif, Fahmi F.; Bakır, Mehmet; Dalgaç, Şekip; Karaaslan, Muharrem; Luo, Heng (Elsevier, 2021)In this work, a new metamaterial design is proposed to yield an ultra-thin and dual band metamaterials perfect absorber (MPA) to be operated in the frequency range from 15 to 35 THz. The proposed structure is consisted of ... -
Utilization of a triple hexagonal split ring resonator (SRR) based metamaterial sensor for the improved detection of fuel adulteration
