essential reference guide for researchers and practitionersThis book highlights the symmetry properties of acoustic fields and describes the gauge invariance approach, which can be used to reveal those properties. Symmetry is the key theoretical framework of metamaterials, as has been demonstrated

History of Gauge Theory,ered as a milestone in the theory of gauge invariance in physics. The gauge invariance in acoustic field equation in curvilinear spacetime and the application of gauge invariance to gravitational wave are briefly introduced.
