Metamaterial-based fuel sensor application with three rhombus slots
(World Scientific Publishing Co. Pte Ltd, 2019)
In this paper, a sensor structure operating in the microwave frequency band is used and it is aimed to determine whether fuel samples are branded or not. In the literature, the studies on the sensor applications of ...
Characterization of tunable electromagnetic band gap material with disordered cavity resonator for X band imaging applications by resistive devices
(Springer, 2019)
Electromagnetic band gap (EBG) integrated monopole antenna is investigated in deformed cavity resonator in this study. The operation frequency is chosen as X band frequency regime and designs are completed for this frequency. ...
Smart monopole antenna with pattern and frequency reconfiguration characteristics based on programmable metasurface
(Wiley, 2019)
Metasurfaces having ultrathin and planar structure with sub-wavelength unit cell, have recently gained significant potential for use thanks to their control capabilities over the electromagnetic waves from microwave to the ...
Two new control strategies: For hydrogen fuel saving and extend the life cycle in the hydrogen fuel cell vehicles
(Elsevier, 2019)
With the acceleration of the development process of hydrogen fuel cell electric vehicles (HFCEV), it has become very important to maximize the energy stored in the vehicle and to use the vehicle with high efficiency. This ...
Gain-phase margins-based delay-dependent stability analysis of pitch control system of large wind turbines
(Sage Publications Ltd, 2019)
This paper investigates the effect of gain and phase margins (GPMs) on the delay-dependent stability analysis of the pitch control system (PCS) of large wind turbines (LWTs) with time delays. A frequency-domain based exact ...
High Sensitive Metamaterial Sensor for Water Treatment Centres
(Springer International Publishing Ag, 2019)
In this study, a high sensitive metamaterial sensor has been designed to detect quality of water for water treatment centre. The water samples have been obtained and electrical properties have been measured in microwave ...
Minimizing Capacitance Value of Interleaved Power Factor Corrected Boost Converter for Battery Charger in Electric Vehicles
(Kaunas University of Technology, 2019)
A dynamic voltage compensator (DVC) technique is presented for the minimizing of the capacitance value of the interleaved power factor corrected (PFC) boost converter for the battery charger in electric vehicles. This ...
An electromagnetic non-destructive approach to determine dispersion and orientation of fiber reinforced concretes
(Elsevier, 2019)
Including fibers in concretes improves their mechanical properties such as flexural strength, impact load resistance and limited crack propagation. The dispersion, orientation and types of the fibers placed in the concretes ...
Pattern reconfigurable metasurface to improve characteristics of low profile antenna parameters
(Wiley, 2019)
This article proposes a mushroom-shaped electromagnetic band gap (EBG) structure for the antenna parameter enhancement of low profile antennas in 5 to 15 GHz regime. Three different type antennas including a dipole antenna, ...
Some aspects of mass-energy equivalence which appears in left-handed metamaterials
(EDP Sciences, 2019)
In this work, the concept of mass-energy equivalence in left-handed metamaterials is discussed by following Einstein's box thought experiment. Left-handed metamaterials are artificial composite structures that exhibit ...
