: Hi,
: I am writing my own code to develop the dispersion curves for lamb waves in aluminum plate. I am having difficulty in finding the roots to my disperison equations. Can anybody please help me with that??

Hi

try this paper for a start:

Lowe, M.J.S., "Matrix techniques for modelling ultrasonic waves in multilayered media", IEEE Trans. Ultrasonics, Ferroelectrics and Frequency Control, vol. 42, pp. 525-542, 1995.

If it doesn't help you'll have to be a bit more specific where your problem is.

Regards,
Tom
