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 ...
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 ...
U-shaped frequency selective surfaces for single- and dual-band applications together with absorber and sensor configurations
(Institution of Engineering and Technology, 2016)
In this study, the frequency selective surface (FSS), absorbance and sensing applications of new unit cells comprised of single, double and quad U-shaped metallic elements are numerically and experimentally investigated. ...
Realization of Modified Elliptical Shaped Dielectric Lens Antenna for X Band Applications with 3D Printing Technology
(Applied Computational Electromagnetics Society (ACES), 2020)
Placing dielectric lens structures into an antenna's aperture has proven to be one of the most reliable methods of enhancing its gain. However, the selected material and the prototyping method usually limit their fabrication ...
NODIC: a novel distributed clustering routing protocol in WSNs by using a time-sharing approach for CH election
(Springer, 2016)
Due to the battery limitations, energy-efficient routing is one of the most important issues in WSNs. In this paper, a novel distributed clustering routing protocol (NODIC) is proposed. The algorithm makes three main ...
Metamaterial Sensor for Transformer Oil, and Microfluidics
(Applied Computational Electromagnetics Society (ACES), 2019)
Metamaterial sensor which is composed of split square rings to operate in X band for liquid and microfluidics has been proposed in this study. For measurement and simulation, we have designed and manufactured a sample ...
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 ...
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 ...
