... Asymptotic methods can be used depending upon the ratio of the characteristic dimensions of the complex structure to the operational wavelength. For wavelengths much smaller than the characteristic dimensions, geometric and physical optics approximations provide approximate analytic solutions.

... The surrounding water supports the acoustic wavelength while the steel shell of the hull supports multiple elastic waves with wavelengths ranging from one-fifth of the acoustic wavelength to orders of magnitude larger than the acoustic wavelength. Thus the analysis of this system involves a very wide range of wavelengths that are amenable to widely differing analytic techniques.
