Our paper on Kapitza-inspired stabilization in electrical circuits was published in Physical Review Applied on August 8, 2025. In this work, inspired by Kapitza’s inverted pendulum problem, we explore how an analogous approach can be applied to non-Foster electrical circuits. In 1951, Nobel Laureate Pyotr Kapitza developed the mathematical basis and the theory behind the stabilization of an inverted pendulum that was being vibrated at its base with a high-frequency motion, launching the fields of vibrational mechanics and vibrational resonances.

A metastructure that designs metastructures: We have built this metastructure that can operate as a programmable wave-based analog computing machine, performing reconfigurable matrix inversion, root finding, and constraint optimization/inverse design. Our paper was published in Nature Communications on January 21, 2025. Many thanks to Dimitrios Tzarouchis and Brian Edwards. For details, please see: https://rdcu.be/d63Jb

I am deeply honored and humbled to receive the 2024 Chen-To Tai Distinguished Educator Award from the IEEE Antennas and Propagation Society. Here are some photos from the awards ceremony in Florence, Italy last night.
