Investigation of the mechanic, electromagnetic characteristics and shielding effectiveness of concrete with boron ores and boron containing wastes
(Elsevier, 2020)
In this study, mechanical properties electromagnetic (EM), and shielding effectiveness of concrete samples containing boron product and wastes was investigated in details. In order to increase shielding effectiveness 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. ...
Investigation of microwave power limiter for Industrial Scientific Medical band (ISM) applications
(Wiley, 2020)
In this paper, a new design of microstrip power limiter which is based on microstrip technology and zero bias Schottky diode is introduced. In this context, the FR-4 substrate that was characterized by dielectric permittivity ...
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 ...
Mutual Coupling Reduction of Cross-Dipole Antenna for Base Stations by Using a Neural Network Approach
(Mdpi, 2020)
In this manuscript, a resonator layer is presented for the purpose of reducing the mutual coupling effect between each antenna element of a cross dipole antenna. In design processes, an artificial neural network approach ...
Tunable energy harvesting on UHF bands especially for GSM frequencies
(Cambridge University Press, 2018)
Metamaterial-based energy harvesting structures operating at GSM goo and GSM 1800 frequency bands have been proposed. The basic structure is composed of four nested U-shaped elements on the front and back side of the ...
Zinc oxide-tungsten-based pyramids in construction of ultra-broadband metamaterial absorber for solar energy harvesting
(Institution of Engineering and Technology, 2017)
A new broadband absorber is investigated for the entire frequency domain of solar light (infrared, visible light and ultraviolet). While current absorbers in the literature have limited operation frequencies, investigated ...
Electromagnetic Scattering Properties of MWCNTs/Graphene Doped Epoxy Layered with PVC Nanofiber/E-Glass Composites
(Springer, 2020)
In this study, composites composed of glass fiber reinforced-epoxy laminates interleaved with electrospun polyvinylchloride (PVC) nano-fibres were designed for radar absorption investigations. The laminated composites which ...
A Split Meander Line Resonator-Based Permittivity and Thickness Sensor Design for Dielectric Materials with Flat Surface
(Springer, 2018)
A metamaterial-based permittivity and thickness sensor structure for dielectric substrate material has been proposed at the X band frequency regime. The sensor structure is designed by using a split meander line type ...
Dynamical chiral metamaterial with giant optical activity and constant Chirality over a certain frequency band
(Applied Computational Electromagnetics Society (ACES), 2016)
We demonstrate numerically and experimentally a dynamical chiral metamaterial that uniaxially creates giant optical activity and circular dichroism. In addition, the structure gives a high negative refractive index due to ...
