The splitting of dispersion curves for plates fluid-loaded on both sides

For in vacuo elastic plates or plates fluid-loaded on one side, it has been previously shown that dispersion curves for both plate-borne (Lamb) type and, in the latter case, also fluid-borne (Scholte–Stoneley) type fail to cross but repel each other, with the waves simultaneously exchanging their physical character. This study is extended here to the case of a plate loaded by two different fluids, where a quantitative calculation of dispersion curves for water on one side, and a lighter or a heavier fluid on the other, is carried out confirming the existence of two different Scholte–Stoneley waves.
