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 ...
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 ...
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 ...
Artificial neural network approach for locomotive maintenance by monitoring dielectric properties of engine lubricant
(Elsevier, 2019)
In this paper, we proposed an approach for locomotive maintenance systems by observing engine lube oil. The mechanical particles in lube oil give information about locomotive engine system condition. The engine lubricant ...
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 ...
Broad band MA-based on three-type resonator having resistor for microwave energy harvesting
(Taylor and Francis Inc., 2017)
We proposed metamaterial absorber having multi-type split coin resonator based on resistive loads. The numerical simulation results and experimental measurements indicate that broad band absorption with a ratio over 80% ...
Multifunctional metamaterial sensor applications based on chiral nihility
(Springer, 2017)
In this paper, chiral nihility based pressure, density, temperature and moisture content metamaterial sensor applications are investigated in detail. A "chiral nihility'' medium in which both the permittivity and the ...
