Simulated and experimental verification of the microwave dual-band metamaterial perfect absorber based on square patch with a 45(0) diagonal slot structure
(Taylor and Francis, 2021)
In this paper, we designed a dual band metamaterial perfect absorber (MPA) for Ku band applications. The overall ultrathin layer of proposed absorber consists of square patch with 450 diagonal slot structure within a copper ...
Design and study of a metamaterial based sensor for the application of liquid chemicals detection
(Elsevier, 2021)
The detection of chemical samples having close dielectric response is a big challenge as the detection principle is driven by the variations in the dielectric parameters of the investigated samples. In the current work, a ...
Investigation of cotton fabric composites as a natural radar-absorbing material
(Emerald Group Publishing Ltd., 2020)
Purpose The purpose of this paper is to investigate cotton fabric behavior that is exposed to radar waves between selected operation frequencies as an alternative radar-absorbing material (RAM) response. Cotton fabric ...
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 ...
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 ...
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 ...
