Physics manual: add chapter on beam propagation in stratified samples
|Status:||In Progress||Start date:|
The note from gisas/theory/SpecularReflectivity/ should become a chapter or a section in the offline PDF reference.
- Have a uniform notation for X-rays and neutrons (#976)
- Derive continuity conditions at layer interfaces for all polarizations
- Search literature, and add appropriate references
- Review the current note, and possibly remove some details or relegate them into an appendix
