Abstract
A discrete Green´s function is derived for surface acoustic wave device analysis, giving the currents in an infinite array of regular electrodes when a voltage is applied to one electrode. Simple formulas are obtained by using the quasi-static approximation, which assumes the frequency to be such that electrode reflections are insignificant. The function exhibits distortion associated with the nonuniform charge distribution, and is shown to be causal
