Abstract : The patent describes an acoustic wave device, wherein an applied electrical signal is transduced to an acoustic wave, comprising: a substrate capable of propagating the acoustic wave; a conductive structure disposed upon the substrate, including at least three separate conductive paths; a pair of the conductive paths including spaced-apart electrodes; and the third conductive path including field-delineating electrodes which are disposed between the electrodes of the pair of paths. In more detail, each of the condcutive paths of the acoustic wave device include electrodes in the form of parallel elements, linear or planar, disposed upon the substrate perpendicularly to the direction of surface wave propagation, caused by the application of an electrical voltage to the pair of conductive paths, which is transduced to an acoustic surface wave.
