About Prof Jensen Li’s work

Prof Jensen Li works in physics, researching functional wave materials. Metamaterials promise to provide exotic material properties based on tailor-made resonating micro-structures. However, the resonating response of these materials are often subject to limited frequency bandwidth and it is a challenge to tune them in real time, preventing them from being widely adopted in practical situations.

There are two active approaches to breaking these barriers. One is through exploiting material gain and loss, known as non-Hermiticity, as an additional dimension, while the other is through exploiting the time dimension. By dynamically tuning the material properties in real-time with modulation speed comparable to the signal frequency, one can break time-reversal symmetry and achieve significant non-reciprocal effects and other new kinds of wave phenomena, known as time-varying metamaterials.

Prof Li’s goal is to develop the technologies required to construct metamaterials with both non-Hermiticity and time-varying capability by establishing the platforms in both electromagnetic and acoustic domains. The platforms will lead us to new physics and applications based on the unique capabilities of these metamaterials.
