Simulation and lithographic fabrication of a triple band terahertz metamaterial absorber coated on flexible polyethylene terephthalate substrate
(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 ...
Highly sensitive metamaterial-based microwave sensor for the application of milk and dairy products
(Optica Publishing Group (formerly OSA), 2022)
In this work, a novel, to the best of our knowledge, metamaterial-based microwave sensor is designed, numerically simulated, and experimentally tested for milk and dairy products in the frequency range of 8 to 9 GHz. The ...
Improved line–line method for propagation constant measurement of reflection-asymmetric networks
(Elsevier, 2022)
A new formalism using line-line measurements is proposed to improve the accuracy of propagation constant measurement of reflection-asymmetric networks using non-calibrated scattering (S-) parameters. For this measurement, ...
Theoretical and experimental sensing of bone healing by microwave approach
(Wiley, 2022)
A medical imaging system is often required to monitor bone growth or bone healing in patients. X-ray imaging method is one of the most used imaging systems but it affects human health due to the ionizing effect of X-rays ...
A Symmetrical Terahertz Triple-Band Metamaterial Absorber Using a Four-Capacitance Loaded Complementary Circular Split Ring Resonator and an Ultra-Thin ZnSe Substrate
(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 ...
A vanadium dioxide-based metamaterial with quatrefoil and circle loaded structure on flexible polyamide substrate for terahertz applications
(Frontiers Media S.A., 2022)
In this study, a novel broadband metamaterial (MTM) absorber is proposed, which is based on vanadium dioxide (VO2) resonators coated onto a flexible polyamide substrate. The VO2 resonator is in the form of a quatrefoil and ...
Investigation of structural, magnetic and microwave absorption properties of NixCo1-xFe2O4/Ni:ZnO (x:0.0, 0.5, and 1.0) embedded epoxy composites
(Springer, 2022)
In this study, NixCo1−xFe2O4/Ni:ZnO (x:0.0, 0.5, and 1.0) epoxy-based composite structures were manufactured by sol–gel method. The structural, morphological and magnetic characteristics were investigated using X-ray ...
Fractal metamaterial based multiband absorber operating in 5G regime
(Elsevier, 2022)
Multiband absorption is the interest of the microwave communities due to several applications in sensing, filtering, and stealth. Usually, the stacking of metal and dielectric multilayered structures form a multiband ...
Radiation pattern reconfigurable cubical antenna array for 2.45 GHz wireless communication applications
(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 ...
A polarization-insensitive triple-band perfect metamaterial absorber incorporating ZnSe for terahertz sensing
(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 ...
