Description: Joint Mechanical Engineering (MNE) and Engineering and Applied Sciences (EAS) SEMINAR
DATE:
October 16, 2020
TIME:
2:00 p.m. to 3:00 p.m.
LOCATION: https://umassd.zoom.us/j/97680493591 (Passcode: 500)
SPEAKER:
Dr. Chengzhi Shi, Assistant Professor,
GWW School of Mechanical Engineering, Georgia Institute of Technology
TOPIC:
Recent Advances in Physical Acoustics and Applications
ABSTRACT:
Physical acoustics is a branch of science studying the physics of acoustic wave propagation that has existed for centuries. Even with a long history, physical acoustics is still a hot research field with many breakthrough contributions in recent years such as the developments of acoustic metamaterials and the realizations of topological and nonreciprocal acoustics. This seminar will summarize some recent advances in physical acoustics and applications. Specifically, physical acoustics is widely used in underwater communications. Sound wave is the most effective technology for long range underwater communication because of its long propagation distance comparing with radio frequency wave and light. However, the low frequency of sound wave limits the communication speed. Another major application of acoustics is ultrasound imaging. However, because of the existence of skull with strong transmission loss, ultrasound brain imaging through intact adult skull is still challenging. In this seminar, we will discuss the development of high-speed acoustic communications by orbital angular momentum multiplexing and a non-Hermitian complementary acoustic metamaterial for transcranial imaging. These recent advances in physical acoustics broaden its applications in real life.
BIO:
Dr. Chengzhi Shi joined the GWW School of Mechanical Engineering at Georgia Institute of Technology in August 2018 as an assistant professor. Before he joined Georgia Tech, Dr. Shi received his Ph.D. in mechanical engineering from the University of California, Berkeley in 2018. He received his M.S. and B.S. in mechanical engineering from the University of Michigan-Shanghai Jiao Tong University Joint Institute in 2013 and 2010. Dr. Shi's research focuses on the physics of acoustic wave propagation, the developments of new acoustic metamaterials, and their applications for underwater communications, biomedical imaging, and noninvasive treatments. As of September 2020, he has published nineteen journal papers in high-impact journals including Nature Communications, Proceedings of National Academy of Science, National Science Review, and Physical Review X.
