7. Properties of bulk crystal elastic modes

In this chapter we pause to review some of the properties of bulk elastic modes in isotropic and anisotropic crystals and learn how code within NumBAT can explore these properties. While it doesn’t directly involve calculation of Brillouin gains, this material is helpful in understanding some of the later examples/tutorials.

This material is most naturally explored interactively and so examples in this chapter are written as Jupyter notebooks stored in the examples/bulkprops directory. (See Tutorial 9 for an introduction to NumBAT in Jupyter).
