Wavefront Interpretation of Sem Resonances, Turn-On Times, and Entire Functionsfrequencies of the scatterer. Since the resonances describe global wave fields that encompass the scattering object as a whole, the SEM series representation encounters convergence difficulties at early observation times when portions of the object are as yet unexcited. Deficiencies in this represen

Transform Relations Between Rays and ModesThe sound field produced by a point source in a stratified wave-guide can be expressed in three different representations based on different approaches to solve the boundary value problem, namely.:

Rays in Tapered WaveguidesThe study of propagation in optical dielectric tapered waveguides is reported. A numerical method based on ray optics and associated energy flux is applied in order to evaluate radiation characteristics of different tapered geometries.

Spectral Synthesis and Adiabatic Invariants for Non-Uniform Waveguidesaccount of wave propagation in such translation invariant waveguides can be formulated. This procedure is one example of the method of separation of variables, whereby some symmetry of the geometry permits the coordinate associated with that symmetry to be integrated out of the problem.
