Ahmed Omar received the B.Sc. and M.Sc. degrees in electrical engineering from Benha University, Benha, Egypt, in 2005 and 2010, respectively, and the Ph.D. degree in electrical engineering from Nanyang Technological University, Singapore, in 2019.From August 2018 to February 2019, he was a part-time Research Assistant at the School of Electrical and Electronic Engineering, Nanyang Technological University. From April 2019 to November 2021, he joined the Department of Electrical Engineering, Pohang University of Science and Technology (POSTECH), Pohang, South Korea, as a Postdoctoral Research Associate. He was with the Department of Electrical and Computer Engineering, University of Wisconsin-Madison, Madison, WI, USA, as a Postdoctoral Research Associate from November 2021 to August 2022. Since August 2022, he has been with the Electrical Engineering Department, King Fahd University of Petroleum and Minerals as an Assistant Professor.His current research interests include the analysis and design of frequency-selective surfaces/structures, absorptive frequency-selective transmission/reflection structures, microwave absorbers, polarization rotators, and compact, wideband, and dual-polarized mm-Wave 5G antennas, and reflector/lens and reflect array antenna.Dr. Omar was the recipient of the Singapore International Graduate Award from the Government of Singapore to pursue the Ph.D. in 2014, the Best Student Paper Award 2018 (Honorable Mention) by the IEEE Singapore MTT/AP Joint Chapter-2018 Best Student Paper Contest, and was shortlisted for the NTU-EEE Best Ph.D. Thesis Award 2019. In 2020, he won the 2020 POSTECH Initiative for fostering Unicorn of Research & Innovation Fellowship.He is listed among the outstanding Reviewer of IEEE TRANSACTION ON ANTENNAS AND PROPAGATION (for the period from May 2020 to April 2021), and IEEE ANTENNAS AND WIRELESS PROPAGATION LETTERS (for the period from January 2020 to December 2020). He is a regular Reviewer for top-tier journals, including IEEE Transactions on Antennas and Propagation, IEEE Transactions on Microwave Theory and Techniques, IEEE Transactions on Electromagnetic Compatibility, IEEE Antennas and Wireless Propagation Letters, IEEE Open Journal of Antennas and Propagation, and IEEE ACCESS.Dr. Omar is currently serving as an Associate Editor for the IEEE Open Journal of Antennas and Propagation and Alexandria Engineering Journal-ELSEVIER, EM section.
