A four element stringray-shaped MIMO antenna system for UWB applications
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
This paper presents a CoPlanar-Waveguide (CPW)-fed stingray-shaped Ultra-WideBand (UWB) Multiple-Input–Multiple-Output (MIMO) antenna system designed for microwave imaging applications. Featuring a diagonal square with ...
Plasmonic titanium nitride nanohole arrays for refractometric sensing
(American Chemical Society, 2023)
Group IVB metal nitrides have attracted great interest as alternative plasmonic materials. Among them, titanium nitride (TiN) stands out due to the ease of deposition and relative abundance of Ti compared to those of Zr ...
Cross-sectional warping and precision of the first-order shear deformation theory for vibrations of transversely functionally graded curved beams
(Springer Science and Business Media B.V., 2023)
The warping may become an important factor for the precise transverse vibrations of curved beams. Thus, the first aim of this study is to specify the structural design parameters where the influence of cross-sectional ...
Cyber-WISE: A cyber-physical deep wireless indoor positioning system and digital twin approach
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
In recent decades, there have been significant research efforts focusing on wireless indoor localization systems, with fingerprinting techniques based on received signal strength leading the way. The majority of the suggested ...
Side-edge dual-band MIMO antenna system for 5G cellular devices
(Elsevier GmbH, 2024)
An eight-element multiple-input multiple-output (MIMO) antenna system is presented for two distinct 5G allocated bands, i.e., 3.5 and 5.2 GHz. The MIMO radiating elements are printed on each side of the mobile phone chassis, ...
Ionic liquid based treatment - A potential strategy to modify bacterial cellulose
(Wiley, 2023)
The constant need for advanced materials led by modern research continues the exploitation of old remedies and innovation to find new solutions. The use of ionic liquids (ILs) as solvents has revolutionized modern chemical ...
Surgical and transcatheter pulmonary valve replacement in patients with repaired tetralogy of Fallot: Cardiac magnetic resonance imaging characteristics and morphology of right ventricular outflow tract
(Springer, 2023)
BackgroundPulmonary valve replacement is recommended in patients with repaired tetralogy of Fallot based on cardiac magnetic resonance imaging (MRI) criteria. This procedure is performed by surgical or transcatheter ...
FDTD-based SAR calculation of a wearable antenna for wireless body area network devices
(Cambridge University Press, 2023)
Wireless-connected wearable electronics are finding extensive usage for diagnostic and therapeutic purposes after the globally spread pandemic disease of COVID-19. Although they are undoubtedly helpful for keeping physical ...
Optimizing percutaneous pulmonary valve implantation with patient-specific 3D-printed pulmonary artery models and hemodynamic assessment
(Frontiers Media SA, 2024)
Background: Percutaneous pulmonary valve implantation (PPVI) has emerged as a less invasive alternative for treating severe pulmonary regurgitation after tetralogy of Fallot (TOF) repair in patients with a native right ...
Sequency index modulation: A novel index modulation for delay-sequency domain waveforms
(Institute of Electrical and Electronics Engineers Inc., 2023)
In this letter, the sequency domain is introduced as a novel resource to propose a new index modulation, which is named sequency index modulation (SeIM). In SeIM, information bits are implicitly conveyed through the indices ...
