Abstract :
A unique feature of the acoustoelectric scattering of the non-uniform SAW beams by the straight metal strips placed on the piezoelectric substrates is underlined. Closed-form solution is obtained to describe the diffraction influence on the reflective delay line properties. The found results allow fast simulation and optimization of SAW tags with high capacity taking into account the diffraction effect consistently.
