ABSTRACT
SBS occurs in all states of matter: gases, liquids, solids and plasmas. A vast number of SBS media have been used in a wide variety of experiments over the years, such that it is very difficult to cover a complete list and to fully reference the work of so many authors in the field. The aim of this chapter is to provide a good starting point for the range of suitable materials, with cited papers (2.1-2.47) giving more references for the interested reader.
