Figure 7

Frequency spectra of (a) the phase velocity and (b) the semilogarithmic plot of attenuation for the symmetric modes (red lines) and antisymmetric modes (black lines) for the thermoelastic waves propagating at 45° orientation to the -axis in a copper foil under the initial state with uniaxial prestress applied in the -direction.
