Abstract: Electroelastic 2D fields excited by a straight general line source in an anisotropic periodically layered piezoelectric medium are expressed in an implicit analytical form of well-convergent Fourier integral. The analysis is given in terms of the 8 × 8 propagator matrix constructed for a graded or stratified medium formed by a periodic succession of layers. The general line source represents a combination of the straight 4D dislocation with the force and charge distributed along the same line.
