Beskrivelse
Caustics, Catastrophes and Wave Fields in a sense continues the treatment of the earlier volume 6 'Geometrical Optics of Inhomogeneous Media' by analysing caustics and their fields on the basis of modern catastrophe theory. The present volume covers local and uniform caustic asymptotic expansions: The Lewis-Kravtsov method of standard functions, Maslov's method of canonical operators , Orlov's method of interference integrals, as well as their modifications for penumbra, space-time, random and other types of caustics. All the methods are amply illustrated by worked problems concerning relevant wave-field applications.
