Applied Propagation Physics Group
The Applied Propagation Physics Group (APPG) is a multidisciplinary research and engineering team devoted to advancing scientific understanding and technological innovation in underwater acoustics, signal processing, and robotics. Led by Professor Y.-T. Lin and comprising numerous engineers, staff, postdoctoral scholars, and students, we strive to improve our ability to characterize the undersea environment.
About Us
Established in 2023, APPG focuses on the development of advanced acoustic and signal processing techniques for underwater applications. We are a seagoing group, with our members frequently embarked on research vessels conducting field experiments throughout the world’s oceans. Our research spans a wide range of topics, including:
- Underwater acoustic propagation theory and modeling
- Acoustical oceanography
- Physical oceanography
- Geoacoustic inversion
- Marine robotics development and employment
- Signal processing
- Distributed acoustic sensing
APPG is part of the Marine Physical Laboratory at the Scripps Institution of Oceanography, UC San Diego. Our lab facilities are located at Scripps Institution of Oceanography in La Jolla, California, and at the Nimitz Marine Facility in Point Loma, California.
