Abstract :
At the 2000 IEEE International Ultrasonics Symposium, we presented a polynomial approach to study guided waves in infinite homogeneous solid cylinders. In this article, we extend equations to infinite homogeneous hollow cylinders. The crystalline axis Z is coincident with the cylinder axis and lateral surfaces are stress-free. Dispersion curves are presented for both a thin and a thick cylinders made of a cylindrically orthotropic material
