Fig. 3: PM under CCW and CW rotation.
From: A novel gyroscope based on the slow surface acoustic wave in a phononic metamaterial
a Mode shapes of WGM1 under no rotation, CCW rotation and CW rotation, respectively. The white arrows are the particle velocity vectors around the pillar, indicating vibration trends of WGM1. b Displacement fields of 11-cell PM under CCW and CW rotation. Several center units in the black frame are enlarged for clearer presentation. c Displacement fields of a complete 3-D model under no rotation, CCW and CW rotation. The red dashed line is the midline of the model structure, showing opposite asymmetry between CCW and CW cases
