Yang Zhiyu
Educational Background
Graduated with a Bachelor's degree from the Department of Physics, Fudan University.
Subsequently selected for the "CUSPEA" (Li Zhengdao) program to study in the United States, where he earned a Ph.D. in Physics from Purdue University.
Academic Career
Joined the Department of Physics at the Hong Kong University of Science and Technology (HKUST) in 1992.
Appointed Full Professor in 2007, a position he has held to date.
Research publications have been cited over 10,700 times, with citations increasing at a rate of approximately 100 per month.
Research Contributions
Professor Yang Zhiyu, along with his team at HKUST, pioneered the field of locally resonant acoustic metamaterials. Their groundbreaking research, published in top-tier international journals such as Science, Nature, and Physical Review Letters, has led the scientific and engineering advancements in this area for over two decades.
Key Innovations
Invented high-performance prototype devices including:
Thin-film acoustic metamaterials for sound insulation
Ultra-black acoustic metamaterials
Ventilated sound insulation metamaterials
Low-frequency micro-vibration dampers
Established a robust theoretical framework and developed a comprehensive intellectual property portfolio, including the world's first:
Thin-film acoustic metamaterial (2008, U.S. patent)
Low-frequency perfect sound-absorbing acoustic metamaterial (2013, U.S. and Chinese patents)
Thin-film vibration damper (2015, U.S. and Chinese patents)
Vibration-damping sound insulation panel (2016, U.S. and Chinese patents)
Ventilated sound insulation device (2017, U.S. and Chinese patents)
Recognition
Awarded the inaugural Brillouin Medal in 2013 by the International Phononics Society, shared with two other pioneers in the field.
Invited to speak at the Summer Davos World Economic Forum in 2015 to present the exceptional vibration and noise reduction capabilities of acoustic metamaterials.
Entrepreneurship
In 2019, Professor Yang founded Lingbo Yisheng Technology (Shenzhen) Co., Ltd., a company that possesses a globally leading and unique core technology platform in acoustic metamaterials. Under his leadership, the company has successfully bridged the gap between metamaterial theory and practical applications, developing three series of industrialized products that are several years ahead of global competitors:
Lightweight sound insulation panels
Ventilated sound insulation devices
Low-frequency micro-vibration dampers
Business Approach
The company designs customized solutions based on clients' specific needs and noise source characteristics, supported by实测数据 and theoretical simulations. It provides key acoustic metamaterial components that are easy to install and reasonably priced, ensuring post-installation performance meets designed sound insulation and ventilation (if required) targets, achieving National Class A environmental standards.
