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 ...
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 ...
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 ...
The Detection of Chemical Materials with a Metamaterial-Based Sensor Incorporating Oval Wing Resonators
(MDPI, 2020)
The detection of branded and unbranded chemical materials is essential for the quality control assessment. In this work, a metamaterial inspired sensor is designed and fabricated, which incorporates oval-shaped wing ...
Pattern reconfigurable metasurface to improve characteristics of low profile antenna parameters
(Wiley, 2019)
This article proposes a mushroom-shaped electromagnetic band gap (EBG) structure for the antenna parameter enhancement of low profile antennas in 5 to 15 GHz regime. Three different type antennas including a dipole antenna, ...
Metamaterial-based energy harvesting for GSM and satellite communication frequency bands
(SPIE - Society of Photo-Optical Instrumentation Engineers, 2018)

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 ...
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 ...
Utilization of a triple hexagonal split ring resonator (SRR) based metamaterial sensor for the improved detection of fuel adulteration
(Springer, 2021)
In this work, a triple hexagonal split ring resonator incorporated metamaterial sensor is proposed for the improved detection of fuel adulteration. The proposed metamaterial structure is made of three resonators, acting ...
