About Me
Dr. Khalid Subhi Ahmad is an academic researcher specializing in antenna design and electromagnetic wave propagation. He is an Assistant Professor at Northern Technical University (NTU) in Mosul, Iraq. He earned his B.Eng. and M.Eng. degrees in Electrical Engineering from the University of Belgrade, Serbia, in 1985 and 1987, respectively. After working as a communications engineer from 1988 to 2003, he transitioned to academia, joining the Foundation of Technical Education (FTE) in 2006. He was promoted to lecturer in 2014 and continued to advance in his academic career. He earned his PhD in Electrical Engineering with a specialization in Telecommunications from Universiti Tun Hussein Onn Malaysia (UTHM) in 2018. Following the dissolution of FTE in 2017 and the formation of Northern Technical University (NTU), He was promoted to Assistant Professor in 2021.
His research focuses on developing advanced frequency reconfigurable antennas, with particular emphasis on integrating graphene materials and metasurfaces to enhance antenna performance parameters such as gain, bandwidth, and operational flexibility.
He has contributed to this field by designing multi-band, reconfigurable antennas that meet the requirements of modern wireless communications technologies. His work also includes tunable graphene-based materials, enabling dynamic control of antenna properties via voltage-controlled conductivity. In addition, he explores metasurface-based techniques to steer and optimize radiation patterns.
He has published in journals and participated in international telecommunications and antenna technologies conferences. His research portfolio includes:
Design and simulation of graphene-based microstrip antennas.
Reconfigurable antenna systems utilizing metamaterials and metasurfaces.
Integration of innovative materials for tunable antenna performance.
Antennas for THz frequency applications in 5G and 6G systems.
