RFBR project No. 20-07-00139 (2020-2022) “Backward acoustic waves in highly anisotropic materials and structures based on them” Head: Ph.D. Kuznetsova A.S.   One of the types of acoustic waves propagating in the plates are backward acoustic waves with different polarizations. The phase and group velocities of these waves are directed in different directions. The aim … Continue reading Project “Backward acoustic waves in highly anisotropic materials and structures based on them”
