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 ...
Design of a Dual Band Metamaterial Absorber for Wi-Fi Bands
(American Institute of Physics Inc., 2018)
The goal of this work is to design and fabrication of a dual band metamaterial based absorber for Wireless Fidelity (Wi-Fi) bands. Wi-Fi has two different operating frequencies such as 2.45 GHz and 5 GHz. A dual band ...
New generation chiral metamaterials based on omega resonators with small and smooth chirality over a certain frequency band
(World Scientific Publishing Co. Pte Ltd, 2016)
In this paper, we have designed, simulated and analyzed a new generation chiral metamaterials (MTMs) with two geometries. There are various types of chiral MTM structures in the literature and almost all of them are indented ...
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 ...
Extremely-broad band metamaterial absorber for solar energy harvesting based on star shaped resonator
(Springer, 2017)
A new metamaterial absorber (MA) is investigated and shown numerically for solar energy harvesting for future solar cell applications. The structure consists of two metals and one dielectric layer having different thicknesses. ...
Solar energy harvesting with ultra-broadband metamaterial absorber
(World Scientific Publishing Co. Pte Ltd, 2019)
In this study, a novel metamaterial absorber (MA) is designed and numerically demonstrated for solar energy harvesting. The structure is composed of three layers with different thicknesses. The interactions of three layers ...
Production of new electromagnetic wave shielder mortar using waste mill scales
(Elsevier, 2020)
Electromagnetic (EM) wave shielder mortar can be produced by mixing cement, natural limestone, tap water with mill scale (mill scale-I and mill scale-II) which is one of the biggest disposal area problems of the iron-steel ...
Broad band metamaterial absorber based on wheel resonators with lumped elements for microwave energy harvesting
(Springer, 2018)
A new metamaterial absorber structure is designed and characterized both numerically and experimentally for microwave energy harvesting applications. The proposed structure includes four wheel resonators with different ...
Dynamic and tunable chiral metamaterials with wideband constant chirality over a certain frequency band
(Elsevier GmbH, 2015)
We present numerically and experimentally a dynamic chiral metamaterial (MTM) that creates strong optical activity and circular dichroism. The proposed tunable structure has a very simple and more efficient configuration ...
