ABSTRACT:
A tunable surface wave resonator is disclosed comprising a substrate of piezoelectric material having acoustic surface wave absorbing extremities, a pair of spaced acoustic surface wave gradient reflectors positioned adjacent to the absorbing extremities of the substrate, a pair of spaced multiphase surface wave tuning transducers selectively positioned between the pair of gradient reflectors over antinode positions of desired resonant frequency standing wave, and an acoustic surface wave transducer selectively placed for optimum coupling of energy into the acoustic resonant cavity formed by the pair of gradient reflectors.
