OverviewAI-generated summary
Samir El‐Ghazaly is a Distinguished Professor at the University of Arkansas at Fayetteville. His research focuses on the physics-based modeling and characterization of electronic devices, particularly in the millimeter-wave spectrum. Recent publications investigate the impact of wave propagation on figures of merit in millimeter-wave transistors, the global modeling of these transistors, and the effects of pad layout variations on their cut-off frequency. He has also explored modeling and machine learning algorithms for antennas, including choke horn antennas and choke ring circular waveguide antennas.
El‐Ghazaly has secured federal funding from the National Science Foundation (NSF) for several projects, totaling nearly $150,000. These grants include support for travel and conference participation in workshops on communication systems and microwave technologies, as well as an I-Corps award for optimizing mm-Wave transistors for 5G applications. His work on advanced semiconductor devices and circuit design is further evidenced by his extensive publication record and collaborations with researchers at the University of Arkansas at Fayetteville, including Amirreza Ghadimi Avval, Soheil Nouri, Sara Ghayouraneh, and Ibrahim N. Alquaydheb.
