Propagation of inhomogeneous plane waves in isotropic solid crystals

In this paper we study the impact of initial mechanical deformation and electric fields applied to linear elastic isotropic solid, on the propagation of inhomogeneous plane waves in such media. We derive the decomposition of the propagation condition for particular isotropic directional bivectors and we show that the specific coefficients are similar to the case of guided waves propagation in isotropic solids subject to a bias.
