We present a complete computation of the surface x1-periodic piezoelectric Green's function based on the asymptotic decomposition method and Poisson's summation formula. Spectral poles associated to surface acoustic waves render plane waves as expected. Behavior at small speed - large slownesses - portrays an oscillatory decay along the transversal direction while logarithmic singularities show up for longitudinal wave-numbers close to zero. At the sagittal plane, singularities arise from the periodic excitation, in accordance to previous 2-D models. Finally, we discuss the fast computation of series and future improvements.
