The Rayleigh-Lamb wave propagation in dielectric elastomer layers subjected to large deformations

► The propagation of electro-elastic waves in dielectric elastomer layers is determined. ► Dispersion relation between wave speed and length in term of bias fields is derived. ► Analysis of the dispersion relation reveals how the bias field influences waves speed. ► Certain bias field result in annihilation of the wave speeds for certain wavelengths. ► The results hint at the ability of constructing isolators with dielectric elastomers.
