Two classes of topological acoustic crystals
This thesis studies two classes of unconventional acoustic crystals. The first class of the acoustic crystal is a two-dimensional crystal with topologically gapped band structure. Circulating flow is introduced into each unit cell to play the role of vector potential. We present a theoretical model...
