Mason Matrazzo KM4SII, radio science and engineering research competition winner

I'm particularly proud to highlight Mason Matrazzo, KM4SII, who in addition to being a noted ham radio operator and DX'er in his own right, is the grandson of Dan and Marlo Matrazzo.  (Marlo is my wife Jane's lifelong friend from childhood.)  

Mason is a first-year PhD student in the Department of Electrical and Computer Engineering (ECE), and is is the first Auburn University student to win the Ernest K. Smith Student Paper Competition.  Needless to say, we are all pretty proud of Mason!

Part of the National Radio Science Meeting, the competition was held Jan. 6–9 in Boulder, Colorado. The meeting was co-sponsored by the Institute of Electrical and Electronics Engineers Antennas and Propagation Society and the National Academies of Science, Engineering and Medicine and organized by the U.S. National Committee for the International Union of Radio Science.

Mason's study, “Parametric Modeling and Analysis of Lightning Sferic Waveforms for D-Region Remote Sensing,” demonstrated how radio waves generated by lightning can be used to track changes in the lowest region of the ionosphere — a layer of the atmosphere that affects long-distance communication.

This work could help scientists better determine ​the way the ionosphere varies over time and space, enhancing the understanding and prediction of how critical communication systems are affected by changes, including space weather events such as solar flares.

“When you have a lightning strike, it emits light, obviously, because you can see that. But it also will emit radio wave emissions over a wide range of frequencies,” explained Mason, who earned a bachelor’s degree in wireless engineering from Auburn in 2025 and is now a first-year graduate student mentored by Hunter Burch, assistant professor in the Department of Electrical and Computer Engineering and the department’s graduate program officer.

“Most of these emissions are concentrated in the very low frequency spectrum. The cool thing about those waves is when they propagate out from the lightning strike, they bounce back and forth between the Earth’s surface and a particular layer of the ionosphere and they’ll travel long distances. As those waveforms bounce along, their characteristics change based on the characteristics of the ionosphere that they’re interacting with, and you can look at those changes and infer what’s happening in that region of the atmosphere.”

Mason's prize was part of a strong week at the National Radio Science Meeting for Auburn engineering. The college sent 12 researchers, presenting 10 papers across three research areas focused on electromagnetic fields, ionospheric radio propagation and plasma waves.

“Each of our students worked hard for this meeting and represented themselves and Auburn well on the national stage,” Burch said.

“We were also very excited to see Mason recognized. I was probably more excited than even he was, because for me this is recognition not just of his hard work and talent but also the quality of the research and education in our program. The fact that a first-year graduate student can compete against top schools and win at the national level says a lot of good things about him and it says a lot of good things about what we're doing here at Auburn.”

Way to go Mason!
