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 ...
Development of GPS and GIS-Based Monitoring System for the Quality of Excavated Coal
(Technical University of Kosice, faculty Berg, 2018)
Because of the advancement of geospatial technologies such as GIS and GPS integration, many mining companies have started to use the technology for mine planning, analysis and management. In this context, this study focuses ...
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 ...
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. ...
Overview of the next quarter century vision of hydrogen fuel cell electric vehicles
(Elsevier, 2019)
Last three decades, costumers and manufacturers of automotive sector have been influenced positively by Hydrogen and fuel cells (FCs). The main goal of automakers can be pointed as minimizing the fuel consumption and exhaust ...
Aircraft selection by applying AHP and TOPSIS in interval type-2 fuzzy sets
(Elsevier, 2020)
The selection of the appropriate aircraft can bring competitive advantages to airlines, however, there are a number of factors which introduce a degree of uncertainty to the selection process. By removing this uncertainty, ...
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 ...
Analysing the performance, fuel cost and emission parameters of the 50 MW simple and recuperative gas turbine cycles using natural gas and hydrogen as fuel
(Elsevier, 2020)
In the present study, firstly, the power production, thermal and exergy efficiencies were calculated for the simple and recuperative gas turbine cycles at constant power production (50 MW) and turbine outlet temperature ...
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 ...
