Abstract :
The first U-path surface-acoustic-wave (SAW) reflective array compressor (RAC) employing reflective arrays of thin metal dots on lithium niobate is reported. The thin rectangular metal dots are made together with the transducers in a single photolithographic step. Performance comparable with that of large time-bandwidth, conventional, grooved RACs is demonstrated, in good agreement with the design.
