Dr. Sichen Yuan
Dr. Sichen Yuan, assistant professor in the Department of Aerospace Engineering and Mechanics, received the Office of Naval Research Young Investigator Award for advancing high-power microwave systems with optimal structural development of lightweight, deployable and reconfigurable cable-network mesh reflector antennas for harsh military environments.
The Office of Naval Research Young Investigator Program is an award supporting early-career academic scientists and engineers in their first or second tenure-track position who earned their doctorate within the past seven years and demonstrate exceptional promise for creative research.
“Receiving the award acknowledges the scientific foundation I have built while also signaling confidence in my future potential to shape the direction of the field,” Yuan said. “This award represents more than an individual achievement. It provides not only resources but also the responsibility to pursue bold ideas, mentor the next generation of engineers and scientists, and strive toward becoming a leading contributor in this research area.”
Unlike traditional rigid, heavy antennas for high-power microwave systems, Yuan’s lightweight, deployable, reconfigurable cable-network mesh reflector functions like a tensioned net that can be folded compactly for transport rather than a solid metal dish.
In addition to its portability, Yuan has made the reflector’s antenna self-healing, safeguarding against extreme temperatures, wind and combat damage in harsh environments.
“Nature often achieves strength through tension and flexibility rather than bulk and rigidity, and I try to apply similar principles in my work,” Yuan said. “At the same time, I value mathematical rigor and careful modeling because strong theory allows us to predict performance before building expensive prototypes.”
Yuan’s classroom method mirrors his approach to research. He encourages students to explore topics that excite them, believing that ownership of their ideas makes students more confident, creative and driven.
“Because my research combines theory, modeling, experiments and prototyping, students learn how those equations guide design decisions. I encourage curiosity and initiative. Engineering is not about memorizing formulas; it is about thinking critically, testing ideas and learning from failure,” Yuan said.
