Applying machine learning approach in recycling
(Springer, 2021)
Waste generation has been increasing drastically based on the world’s population and economic growth. This has significantly affected human health, natural life, and ecology. The utilization of limited natural resources, ...
Seismic metamaterials for low-frequency mechanical wave attenuation
(Springer, 2021)
In this study, a triangular array of cylindrical holes was shown to function as a local resonator to seismic metamaterials against the vibration generator loading in the geophysics concept. The field test showed that the ...
Optimizing the Gain and Directivity of a Microstrip Antenna with Metamaterial Structures by Using Artificial Neural Network Approach
(Springer, 2021)
The purpose of this study is to improve the gain and directivity of the microstrip patch antenna by means of metamaterial (MTM) structures. As it is known, antennas have power densities in a certain direction, and the ...
Improved Modeling of Microwave Structures Using Performance-Driven Fully-Connected Regression Surrogate
(Institute of Electrical and Electronics Engineers Inc., 2021)
Fast replacement models (or surrogates) have been widely applied in the recent years to accelerate simulation-driven design procedures in microwave engineering. The fundamental reason is a considerable-and often prohibitive-CPU ...
Microwave absorption performance of hexagonal nano boron nitride doped basalt fabric-reinforced epoxy composites
(Emerald Group Publishing Ltd., 2021)
Purpose: The purpose of this paper is to investigate the effect of doping element on the microwave absorption performance of hexagonal nano boron nitride (h-nBN)-reinforced basalt fabric (BF)/epoxy composites. A new type ...
Monopole antenna integrated cavity resonator for microwave imaging
(SPIE, 2021)
We present a system that displays an image of any metal structure in a scene by the use of microwave radiation from a cavity resonator in a 10-GHz frequency band. An 80 mm x 80 mm mushroom-like electromagnetic band gap ...
Hypersensitized Metamaterials Based on a Corona-Shaped Resonator for Efficient Detection of Glucose
(MDPI, 2021)
In this work, a new design for a real-time noninvasive metamaterial sensor, based on a corona-shaped resonator, is proposed. The sensor was designed numerically and fabricated experimentally in order to be utilized for ...
Wideband Microwave Absorber Comprising Metallic Split-Ring Resonators Surrounded With E-Shaped Fractal Metamaterial
(Institute of Electrical and Electronics Engineers Inc., 2021)
A specially designed metallic E-shaped fractal-based perfect metamaterial absorber (PMA) with fairly wideband absorptivity in the K- and Ka-bands of the microwave regime was investigated. The PMA top surface is comprised ...
Hirshfeld Surface Analysis, Interaction Energy Calculations of Metal (II) 4-Cyanobenzoate with Nicotinamide / N,N'-Diethylnicotinamide Complexes
(Journal of the Turkish Chemical Society, Section A: Chemistry, 2021)
Hirshfeld surface analysis, a suitable tool for investigating intermolecular interactions, has been widely used in crystallography in recent years. A breakdown of related fingerprint graphics is presented as a color chart, ...
Experimental verification of phononic crystal based on square arrays of cylindrical holes against seismic vibrations in full-scale systems: modeling, sensing and signal processing of seismic vibrations
(Springer, 2021)
In this study, phononic crystals reducing the earthquake effects will be determined and prototypes will be constructed which can give the opportunity to reduce the effects of seismic waves. Furthermore, test results will ...
