Normal Mode Solutions in Underwater Acoustics
The mathematical foundation of acoustics is the wave equation. The origins and parameters of the wave equation will be discussed in the context of the underwater environment. Using the Fourier transform, the wave equation can be reduced to the Helmholtz equation, for which single frequency solutions can be obtained with a number of analytic techniques. The method of normal modes will be presented in general and applied to some classic examples in underwater acoustics. Challenges and limitations associated with computational normal mode solutions will be mentioned.
