An IEEE Fellow, Yahya Rahmat-Samii is the Northrop Grumman Chair Distinguished Professor at the University of California, Los Angeles. Dr. Rahmat-Samii’s pioneering contributions to developing sophisticated antennas can be seen in billions of cell phones, millions of satellite dish antennas, and space technology for remote sensing and planetary missions. Dr. Rahmat-Samii developed innovative methods for analyzing and designing modern reflector antennas important to NASA’s space research. He was one of the inventors of the plane-polar near-field technique used to measure the performance of the Galileo spacecraft antenna. He was a principal developer of the microwave holographic diagnostic technique used to improve the performance of NASA’s Deep Space Network. His important research on how electromagnetic waves interact with human tissue led to the development of internal antennas for cellular phones that are a key component of modern handsets. His work on genetic and particle swarm algorithms for electromagnetic optimization has been successfully used by universities and companies designing antennas for wireless communications.
