Abstract:
1. An electro-acoustic cloaking transducer system for cloaking a targeted object including transducer means, said targeted object having front and rear object ends, said system to provide an acoustic transduction cloak on or about the targeted object so that incoming sound appears to pass through the targeted object without reflecting sound from the targeted object and also leaving no acoustic shadow so as to thus appear 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 object ends of the targeted object and circuit means disposed on the targeted object and inter-coupling the front and rear transducers, said front transducer positioned to absorb an impinging wave front substantially without reflections and said rear transducer positioned for re-transmitting the wave front at the rear side, said circuit means comprising electrical wiring connected between the front and rear transducers providing bi-directional signal transmission between the front and rear transducers.
