Title: A survey of applications of ray phase-space eikonal methods in linear wave conversion
Abstract: The problem of linear wave conversion involves the exchange of wave action between two waves of different types (i.e., satisfying different linear dispersion relations) as they interact in a nonuniform medium. Since uncoupled waves travel on a distinct dispersion manifold in ray phase space, whose coordinates (x, k) include the position x of a ray and its canonically-conjugate wavevector k, it is convenient to use eikonal methods to study the intersection (in ray phase space) of two rays of different types and construct a scattering matrix describing the transmission and conversion of wave action between the two waves. In particular, we demonstrate the modular nature of these ray phase-space eikonal methods.
