About

Gengkai Hu is a pioneering figure in the field of metamaterials and wave control, whose work has fundamentally reshaped how scientists design materials to manipulate acoustic and elastic waves. His research centers on transformation optics, cloaking, and the inverse design of smart transducers, with a particular focus on achieving unprecedented control over wave propagation through innovative material architectures. Hu’s major contributions include the development of in-plane semi-linear cloaks with arbitrary shape, a breakthrough that demonstrated how to render objects invisible to elastic waves without the constraints of traditional linear cloaking methods. This work, published in 2019 and garnering 8 citations, laid the groundwork for more flexible and practical cloaking devices. More recently, Hu introduced a piezoelectric gauge transformation for the inverse design of polar Willis transducers, a novel approach that enables the creation of advanced acoustic sensors and actuators with tailored properties. This 2025 paper, with 1 citation, showcases his continued leadership in merging theoretical elegance with real-world application. Hu’s impact is measured not only in citations but in the conceptual tools he has provided—his work inspires a new generation of researchers to explore the boundaries of wave-matter interaction, from stealth technology to energy harvesting.
