An introduction to the properties of wavelike excitations associated with surfaces and interfaces. The emphasis is on acoustic, optic, and magnetic excitations, and, apart from one section on liquid surfaces, the text concentrates on solids. The important topic of superlattices is also discussed, in which the different kinds of excitation are considered from a unified point of view.
