The homogeneous isotropic electro.microstretch viscoelastic solids have been
taken into consideration for investigating the propagation of plane waves and fundamental
solution. For two dimensional model, it is found that there exists two coupled longitudinal
waves namely longitudinal displacement (LD) wave and longitudinal microstretch (LM) wave
and two coupled transverse displacement and transverse microrotational waves (CD-I and
CD-II). The phase velocities, attenuation coefficients, specific loss, penetration depth are
computed numerically. The resulting quantities are depicted graphically to show the viscous
effect. In addition, we construct the fundamental solution of the system of differential
equations in the theory of an electro-microstretch viscoelastic solids in case of steady
oscillations in terms of elementary functions. Some basic properties of the fundamental
solution are established. Some special cases are also discussed.
