Analysis of ray phase-space recirculation in an extended Budden problem

A. J. Brizard, A. N. Kaufman, E. R. Tracy

A three-wave Budden model with two resonance layers is constructed that allows recirculation of energy fluxes along a quadrangle in ray phase space. The transmission, reflection, a…

Local Solutions for Generic Multidimensional Resonant Wave Conversion

E. R. Tracy, A. N. Kaufman

In more than one spatial dimension, resonant linear conversion from one wave type to another can have a more complex geometry than the familiar 'avoided crossing' of one-dimensiona…

Ray helicity: a geometric invariant for multi-dimensional resonant wave conversion

E. R. Tracy, A. N. Kaufman

For a multicomponent wave field propagating into a multidimensional conversion region, the rays are shown to be helical, in general. For a ray-based quantity to have a fundamental…
