guided waves

Hello everyone, i have two basic doubts regarding guided waves.

1. The physics behind the occuring of number of modes in thin plates (guided waves) rather than in thick plates?

2. what is the main use of dispersion curves in guided waves?

please help me in clearing these doubts.

: Hello,
: 1) The possible thickness of the plate depends on the material of the plate.
: 2) Dispersion curves give the wave velocity against the frequency*thickness of the plate for each mode.
: See "Dispersion Curves in Guided Wave Testing" - Link below.
