Dispersion Curve in plate

I am studying elastic waves and metamaterial which exhibits some extraordinary phenomena.
What I am curious about is how to obtain the dispersion curve of the lamb wave.
As I refer to this video (www.youtube.com/watch v=HMgdXMNigCA&t=292s), there are some questions.
1) As far as I know, the lamb wave propagates through the plate while the "verticial displacement" changes.
Thus, I can't understancd how we get the dispersion curve in 2D.
2) Let's assume the width and height of the rectangular introduced in the video are 10[mm] and 100[mm], respectively. Then what is the thickness of that plate?
Thank you for reading my writing.
