The distributed acoustic reflection transducer has a reflection function which includes at least one reversal of sign, that is to say it possesses at least one reflector and, in general, a combination of reflectors, the center of which is at a distance of k.lambda./2+.lambda./4 from the center of the other reflectors, .lambda. being the wavelength corresponding to the central operating frequency of the transducer. The applications will be for the production of surface-wave filters in radio communication systems.
