Time Reversal Acoustics

Meer over het boek

Focusing on time reversal acoustics, this book delves into its theoretical foundations across the first eleven chapters, exploring its symmetry properties. Subsequent chapters detail four major applications: underwater communication, seismic exploration, nondestructive evaluation, and medical ultrasound imaging, complete with experimental setups and case studies. The author introduces a gauge invariance approach, confirmed through the development of acoustical metamaterials and superresolution applications. Notably, it highlights innovative uses of time reversal acoustics in underwater communication technology.
