Figure 5

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 along the -direction in a copper foil under the natural state (without any prestress) and two initial states with two uniaxial prestresses and applied in the -direction.
