Abstract:

Theories for the interaction of surface waves with internal wave-induced surface currents are reviewed, and applied to the problem of microwave sensing of internal waves. Several types of nonlinearities are discussed, including those associated with the wave-current interaction process within the context of infinitesimal-amplitude wave theory, those associated with nonlinear surface wave dynamics, and those associated with electromagnetic scattering from nonlinear surface waves. Results of a numerical integration of the wave equation are presented and compared with linearized perturbation solutions in order to illustrate some of these nonlinearities.
