Abstract :
A procedure for designing highly reflecting arrays to specified responses in surface acoustic-wave (SAW) devices is proposed. Multiple reflections in the low-loss arrays are fully taken into account. The problem is made tractable by using a 180 degrees reflecting geometry rather than reflecting the SAW twice through 90 degrees .<>
