1. Quartz resonators
1.1 General
Early low-frequency resonators operated on elongation modes. The quartz rod is the seat of a deformation, parallel to the length, propagating parallel to the length of the rod. The propagation velocity v of this deformation depends on the elastic properties of the quartz in this propagation direction:
with :
- c :
- elastic coefficient (Young's modulus for an isotropic material)
- ρ :
- density.
When this shaking reaches one of the ends, a reflected wave...
