Fire Detection Behind a Wall by using Microwave Techniques
(American Institute of Physics Inc., 2018)
In this work, detection of the fire location behind a wall by using microwave techniques is illustrated. According to Planck's Law, Blackbody emits electromagnetic radiation in the microwave region of the electromagnetic ...
90° degrees Polarization rotator and antireflector using meanderline chiral metamaterials: Analytical and numerical approach
(Elsevier GmbH, 2015)
We demonstrate theoretically and numerically a chiral slab that can exhibit optical activity, circular dichroism, and antireflection in detail. Copolar and crosspolar transmitted and reflected waves depending on permittivity, ...
Investigation of the mechanic, electromagnetic characteristics and shielding effectiveness of concrete with boron ores and boron containing wastes
(Elsevier, 2020)
In this study, mechanical properties electromagnetic (EM), and shielding effectiveness of concrete samples containing boron product and wastes was investigated in details. In order to increase shielding effectiveness of ...
Metamaterial sensor application concrete material reinforced with carbon steel fiber
(World Scientific Publ Co Pte Ltd, 2020)
In this paper, a rectangular split ring resonator-type metamaterial (MTM) sensor application is demonstrated in order to examine concrete materials. First, different types of concrete materials including carbon steel fiber ...
Design of metasurface polarization converter from linearly polarized signal to circularly polarized signal
(Elsevier GmbH, 2018)
In this study, we both numerically and experimentally present a metasurface (MS) polarization converter to transform linearly polarized signal into circularly polarized one. The unit cell consists of two rectangular metallic ...
Investigation of microwave power limiter for Industrial Scientific Medical band (ISM) applications
(Wiley, 2020)
In this paper, a new design of microstrip power limiter which is based on microstrip technology and zero bias Schottky diode is introduced. In this context, the FR-4 substrate that was characterized by dielectric permittivity ...
High Sensitive Metamaterial Sensor for Water Treatment Centres
(Springer International Publishing Ag, 2019)
In this study, a high sensitive metamaterial sensor has been designed to detect quality of water for water treatment centre. The water samples have been obtained and electrical properties have been measured in microwave ...
An electromagnetic non-destructive approach to determine dispersion and orientation of fiber reinforced concretes
(Elsevier, 2019)
Including fibers in concretes improves their mechanical properties such as flexural strength, impact load resistance and limited crack propagation. The dispersion, orientation and types of the fibers placed in the concretes ...
Multipurpose chemical liquid sensing applications by microwave approach
(Public Library of Science, 2020)
In this work, a novel sensor based on printed circuit board (PCB) microstrip rectangular patch antenna is proposed to detect different ratios of ethanol alcohol in wines and isopropyl alcohol in disinfectants. The proposed ...
Design of a Dual Band Metamaterial Absorber for Wi-Fi Bands
(American Institute of Physics Inc., 2018)
The goal of this work is to design and fabrication of a dual band metamaterial based absorber for Wireless Fidelity (Wi-Fi) bands. Wi-Fi has two different operating frequencies such as 2.45 GHz and 5 GHz. A dual band ...
