Xuyang Lu has received a pre-doctoral achievement award from the IEEE Solid-State Circuits Society, recognizing his research in wireless sensing and communication technologies.

While the fifth generation (5G) network promises an expansion of wireless technology, it also brings new problems in data efficiency, privacy and bandwidth. As a Ph.D. student in electrical engineering, Lu developed solutions in each of those three areas. The IEEE award honors the breadth of his work.

To address efficiency and privacy, Lu exploited the physical properties of key electromagnetic frequencies to build a new layer of security at the network's most basic level. In some cases, combining this work with data encryption could better safeguard online banking and other sensitive transactions. In other cases, bypassing the need for encryption altogether could reduce lag time in such tools as robotic surgery devices. Lu also designed a new methodology for increasing bandwidth in a wireless transceiver array, improving the way engineers tune wireless signals to allow for a greater range of features.

"The ultimate goal is to develop a stronger and safer future communication platform," he said.

Lu, who was advised by Kaushik Sengupta, associate professor of electrical engineering, completed his Ph.D. requirements on July 20. He joined Princeton in 2014 from Rice University, where he studied integrated circuits and earned a bachelor's degree in electrical engineering, with honors. In 2019 Lu won an Award for Excellence from Princeton's School of Engineering and Applied Science. To date he has published 12 peer-reviewed articles as the first author, and he is a co-inventor on two pending patents.
