Design of a Broadband Coplanar Waveguide-Fed Antenna Incorporating Organic Solar Cells with 100% Insolation for Ku Band Satellite Communication
(Mdpi, 2020)
A broadband coplanar waveguide (CPW)-fed monopole antenna based on conventional CPW-fed integration with an organic solar cell (OSC) of 100% insolation is suggested for Ku band satellite communication. The proposed ...
Determination of Barreling of Aluminum Solid Cylinders During Cold Upsetting Using Genetic Algorithm
(UNIV FED RIO DE JANEIRO, LAB HIDROGENIO, 2019)
This study presents Genetic Programming models for the formulation of barreling of aluminum solid cylinders during cold upsetting based on experimental results. The maximum and minimum radii of the barreled cylinders having ...
Exhibition of polarization conversions with asymmetric transmission theory, natural like chiral, artificial chiral nihility and retrieval studies for K- and C-band radar applications
(Indian Academy of Sciences, 2019)
In this study, asymmetric transmission, natural chirality phenomena and a retrieval study with chiral metamaterials (MTMs) are numerically and experimentally focussed, investigated and discussed by examining the polarization ...
Wet non-thermal integration of nano binary silicon-gold system with strong plasmonic and luminescent characteristics
(Amer Inst Physics, 2019)
We report on a wet none thermal integration of the binary silicon-gold nano system. Instead of thermally based gas-solid procedures, we use charge exchange/injection-based procedures in a chemical wet environment. SEM and ...
Proximal probe-like nano structuring in metal-assisted etching of silicon
(American Institute of Physics Inc., 2019)
We use silicon having multiple crystalline orientation domains and high metal doping in metal assisted chemical etching (MACEtch) in HF/H2O2. In device-quality silicon, MACEtch produces high-aspect ratio anisotropic (1-D) ...
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 ...
Bandwidth Improvement in Bow-Tie Microstrip Antennas: The Effect of Substrate Type and Design Dimensions
(Mdpi, 2020)
In this work, the impact of substrate type and design dimensions on bow-tie microstrip antenna performance and bandwidth improvement is presented both numerically and experimentally at 4-8 GHz. The finite integration ...
Octagonal Shaped Metamaterial Absorber Based Energy Harvester
(Kaunas University of Technology, 2018)
In this study, a novel octagonal shaped metamaterial based broadband absorber is proposed for energy harvesting at WIMAX wireless communication band. The proposal has an absorption of 99.97 % at 5.5 GHz with a bandwidth ...
Electromagnetic simulations of polarization-insensitive and wide-angle multiband metamaterial absorber by incorporating double asterisk resonator
(Indian Acad Sciences, 2020)
A novel multiband metamaterial absorber (MTMA) is proposed which is capable of well presenting a polarization-insensitive and wide incident angle stability in the microwave frequency range. The proposed MTMA comprising two ...
Effect of Different Arc Welding Processes on the Metallurgical and Mechanical Properties of Ramor 500 Armor Steel
(Asme, 2020)
In the present study, Ramor 500 armor steel plates were automatically welded using cold metal transfer arc welding (CMT), gas metal arc welding (GMAW), and hybrid plasma arc welding (HPAW) methods. To investigate the effects ...
