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
