Application of Acoustic Metamaterial to Time-Reversal Acoustics,he time reversal symmetry property of S the solution is given. A geometric structure of a metamaterial for both an electromagnetic wave and acoustic wave is given. Then, the geometric structure of the metamaterial to implement time reversal acoustics is given. Time reversal acoustics has been succes

Underwater Acoustical Cloaking,ilinear coordinates to describe a stationary object’s geometrical structure. The cloaking of underwater objects is an extension of the cloaking of objects in the air. This is more complex than cloaking in the air. The theory of sound propagation underwater is given. The form invariance of the Wester
