 We consider the propagation of guided waves in an elastic strip{(y,z): 0<z<1} with the fixedfixed, fixedfree or freefree boudarycondition. Each guided wave is characterized by an eigenvalue k_n(p)and an associated eigenfunction f_n(p,z) of the operator L(p,D_z)reduced from the elastic operator L(D_y,D_z) using a partial Fouriertransform y > p. We examine the `dispersion curves' k_n(p),especially their asymptotic behavior as p > infinity, thoroughly inisotropic case and to some extent in anisotropic case.
