Design and Analysis of a Compact GSM/GPS Dual-Band Bandpass Filter Using a T-Shaped Resonator
Basit, Abdul; Khattak, Muhammad Irfan; Al-Hasan, Mauth; Nebhen, Jamel; Jan, Atif (Korean Institute of Electromagnetic Engineering and Science, 2022)This study presents an ultracompact dual-band bandpass filter with controllable transmission zeros based on quarter-wave dual-mode resonator for GSM (global system for mobile communications) and GPS (global positioning ... -
Enhanced tunable plasmonic resonance in crumpled graphene resonators loaded with gate tunable metamaterials
Khattak, Muhammad Irfan; Ullah, Zaka; Al-Hasan, Mu’ath; Sheikh, Fawad (OSA - The Optical Society, 2020)Graphene devices have been widely explored for photonic applications, as they serve as promising candidates for controlling light interactions resulting in extreme confinement and tunability of graphene plasmons. The ... -
A frequency and radiation pattern combo-reconfigurable novel antenna for 5g applications and beyond
Shereen, Muhammad Kamran; Khattak, Muhammad Irfan; Al-Hasan, Mu’ath (MDPI AG., 2020)This paper presents a novel combo-reconfigurable architecture for the frequency and radiation patterning of a novel antenna system for future fifth-generation (5G) millimeter-wave mobile communication. The tuning system ... -
Miniaturized MIMO Antenna with Low Inter-radiator Transmittance and Band Rejection Features
Khan, Muhammad Irshad; Khattak, Muhammad Irfan; Al-Hasan, Mauth (Korean Institute of Electromagnetic Engineering and Science, 2021)In this article, compact a multiple-input and multiple-output (MIMO) system with flag-shaped radiators and a mountain-shaped ground plane is presented. Isolation is enhanced with the help of a decoupling stub placed between ... -
On Learning Spectral Masking for Single Channel Speech Enhancement Using Feedforward and Recurrent Neural Networks
Saleem, Nasir; Khattak, Muhammad Irfan; Al-Hasan, Muath; Qazi, Abdul Baseer (Institute of Electrical and Electronics Engineers Inc., 2020)Human speech in real-world environments is typically degraded by the background noise. They have a negative impact on perceptual speech quality and intelligibility which causes performance degradation in various ...
