OverviewAI-generated summary
Amirreza Ghadimi Avval is a researcher with extensive experience in radio frequency (RF) engineering and simulation. His work has focused on the modeling, characterization, and optimization of high-frequency electronic devices and systems. Avval has investigated the impact of wave propagation on figures of merit in millimeter-wave transistors and explored distributed-model-based approaches for the electrical and thermal analysis of Gallium Nitride High Electron Mobility Transistors (GaN HEMTs). His research also extends to the physics-based modeling and characterization of wide GaN-HEMTs and the effects of pad layout variations on the cut-off frequency of millimeter-wave transistors.
Avval's expertise includes employing simulation software such as MATLAB and COMSOL Multiphysics for engineering designs. He has also contributed to the development of machine learning algorithms for antenna modeling, as demonstrated in his recent work on rectangular choke horn antennas. His academic contributions are reflected in a publication record that includes a patented novel device in wireless communication systems. Avval has collaborated with several researchers at the University of Arkansas at Fayetteville, including Samir El‐Ghazaly, Soheil Nouri, Sara Ghayouraneh, and Ibrahim N. Alquaydheb, with whom he shares multiple publications.
