Current events

1. Wiener-Hopf and Wiener-Hopf Elastic Plate Solution need work.
2. Interaction Theory for Infinite Arrays - section on acoustic scattering should be separate section.
3. We need to explain how to calculate Rayleigh-Bloch Waves
4. Infinite Array Green Function needs to be separated, one page for the Green function, the other for how to calculate the far field wave.
5. We need to add content to the Semi-Infinite Array
6. We need to work on Eigenfunction Matching for a Semi-Infinite Dock
