Determination of physical properties of concrete by using microwave nondestructive techniques
(Applied Computational Electromagnetics Society (ACES), 2018)
Determination of the electrical properties of concretes with different water/cement ratios and investigation of the relationship between their electrical and mechanical properties is a promising technique towards improving ...
A Study on Fuel Cell Electric Unmanned Aerial Vehicle
(Ieee, 2019)
This study focused on fuel cell electric unmanned aerial vehicle (FC-EUAV) in order to find solutions to problems such as the short-lived and limited long flight endurance of unmanned aerial vehicles operating with fossil ...
A Power Rating and Application Survey of Magnetically Controlled Shunt Reactor
(Institute of Electrical and Electronics Engineers Inc., 2017)
MCSR can simplify the system reactive power and voltage control in the super / special high-voltage power grid, suppress power frequency and operation over voltage, eliminating generator self excitation, dynamically ...
Grease oil humidity sensor by using metamaterial
(Taylor and Francis, 2020)
Interaction between water and lubrication grease oil is not desirable, but it is not inevitable. The operational life of the machine component is influenced by humid grease oil. Metameterial-based transmission line sensor ...
Microwave metamaterial absorber for sensing applications
(Elsevier, 2017)
A metamaterial absorber (MA) based sensor is designed and analysed for various important applications including pressure, temperature, density, and humidity sensing. Material parameters, as well as equivalent circuit model ...
Performance Results of Photovoltaic/Fuel Cell Based Hybrid Energy System under Variable Conditions
(Ieee, 2019)
In this paper, dynamic operation and optimization of a grid connected hybrid system including photovoltaics (PV) and fuel cell (FC) is presented. For this purpose, abc/dq transform based power flow controller is used in ...
Linear to left- and right-hand circular polarization conversion by using a metasurface structure
(Cambridge University Press, 2018)
By using a metasurface (MS) structure, a linearly polarized wave is converted to circularly polarized waves. Both right- and left-handed circular polarizations (RHCPs and LHCP) are obtained by a simple configuration in the ...
Tunable perfect metamaterial absorber and sensor applications
(Springer, 2016)
Operation frequencies of traditional metamaterial absorbers are fixed meaning that it is not possible to change that frequency after the fabrication. Therefore, more studies are focused on the design of Tunable metamaterial ...
Sensitive Metamaterial Sensor for Distinction of Authentic and Inauthentic Fuel Samples
(Springer, 2017)
A metamaterial-based sensor has been realized to distinguish authentic and inauthentic fuel samples in the microwave frequency regime. Unlike the many studies in literature on metamaterial-based sensor applications, this ...
A Nondestructive Method for Determining Fiber Content and Fiber Ratio in Concretes Using a Metamaterial Sensor Based on a V-Shaped Resonator
(Springer, 2019)
A micro sensor based on a V-shaped resonator (VSR) is implemented for the purpose of determining fiber content and ratio in construction materials as a nondestructive method. Concrete is investigated as the construction ...
