    The ray optical solution to the problem of a time harmonic line charge source radiating acoustic energy into a semi-infinite piezo-electric half space is outlined. This ray optical technique differs from the approach employed in recent publications [1], [2], and leads to a better understanding of bulk-wave radiation in SAW devices. PZT ferroceramic materials have been chosen for this study and numerical results are obtained and given.
