Abstract:
1. An electro-acoustic cloaking transducer system including transducer means, said targeted object having front and rear object ends to provide an acoustic transduction cloak on or about the targeted object so that incoming sound passes through the targeted object without reflecting sound from the targeted object and also leaving no acoustic shadow so as to thus be acoustically invisible, said transducer means comprising at least one pair of transducers including front and rear transducers that are positioned on the respective front and rear ends of the targeted object and electrical circuit means disposed on the targeted object and inter-coupling the front and rear transducers, said front transducer positioned at the front end of the targeted object to absorb an impinging wave front and transmit the absorbed wave front via the electric circuit means to said rear transducer, said rear transducer positioned at the rear end of the targeted object for re-transmitting the wave front received from the electric circuit means at the rear end of the targeted object, said circuit means comprising electrical wiring connected between the front and rear transducers providing bi-directional signal transmission between the front and rear transducers, said re-transmitted wave front reflected from a reflector surface for receiving the re-transmitted wave front that is reflected and passes back through the targeted object between the front and rear transducers via said electrical circuit means emerging as a return wave front from the front transducer, as if the targeted object were absent.
