Abstract: The coupled 2D electro-elastic fields are found in the piezoelectric sandwich structure (substrate-layer-substrate) of unrestricted anisotropy containing the straight-line source parallel to the interfaces. The general line source consists of the four coinciding sources: the line of forces, the charged line, the dislocation line and its electrostatic analogue. The obtained solution is presented in a form of convergent Fourier integral. The integrand is implicitly expressed in terms of the eigenvalues and the eigenvectors of the generalized Stroh matrix. Determination of these eigenvalues and eigenvectors requires additional computing. Specific features of the found fields are analyzed.

Keywords: Piezoelectricity, anisotropy, 1D inhomogeneity, line defect
