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 ...
Investigation of methanol contaminated local spirit using metamaterial based transmission line sensor
(Elsevier, 2021)
A metamaterial-based transmission line sensor was designed to determine the amount of methanol in methanol-contaminated local spirit samples both numerically and experimentally. The proposed sensor consists of a square ...
A monopole microwave-assisted electrochemical sensor for the detection of liquid chemicals
(S.C. Virtual Company of Phisics S.R.L, 2021)
In this paper, a new sensor structure is presented based on a printed circuit board (PCB) monopole antenna with operating frequency of f=2 GHz. Numerical investigation was performed in order to determine the ethanol alcohol ...
Design of a linear to circular polarization converter integrated into a concrete construction for radome applications
(Cambridge University Press, 2021)
In this paper, we present a linear to circular polarization converter integrated in a concrete structure to eliminate signal transmission problem originated from the concrete buildings in microwave regime. Two polarization ...
Radiation pattern reconfigurable cubical antenna array for 2.45 GHz wireless communication applications

Sinusoidally located concrete metastructures for attenuation of seismic surface vibrations
(Springer, 2022)
In this numerical and experimental study, we designed sinusoidal located concrete-based boreholes which are candidate for seismic shielding applications. To attenuate seismic wave transmission in an area, proposed design ...
A study on electronically controllable beamforming monopole antenna for telecommunication applications
(Taylor and Francis, 2022)
The design, analysis, and prototyping of an electronically controllable beamforming monopole antenna (ECBMA), which could be a good candidate for ceil-mounted wireless telecommunication systems, are reported. The proposed ...
Prevention of Wave Propagation via Circular Arrangement of Seismic Metamaterials Formed with Concrete Piles
(MDPI, 2023)
It is known that the low frequencies of seismic surface waves have a destructive effect. The main purpose of seismic metamaterials is to protect structures from seismic waves at low frequencies, especially in a wide band. ...
