Abstract :
A surface-wave reflective-array compressor using edge-bonded transducers and a fused-silica substrate is described. A flat amplitude response over a 60 MHz bandwidth about a 100 MHz centre frequency has been obtained by weighting the groove depth. This is in good agreement with the theoretical calculated transfer function involving a ¿ function method. Insertion loss is 25 dB and a pulse-compression loop has shown a compression ratio of nearly equal to 1.800.
