Abstract :
We study the possibility of using electrodes of varying thickness for strong energy trapping in quartz thickness-shear resonators as an alternative for contoured resonators. A theoretical analysis is performed. Results show that nonuniform electrodes can produce strong trapping of thickness-shear modes
