Claim:
1. A method for use in communicating through an electromagnetic barrier that includes a first surface and an opposing second surface, said method comprising: coupling a plurality of first transducers to the first surface, the plurality of first transducers including a first interior transducer and a plurality of first peripheral transducers spaced circumferentially about the first interior transducer; coupling a plurality of second transducer to the second surface, the plurality of second transducers including a second interior transducer and a plurality of second peripheral transducers spaced circumferentially about the second interior transducer, wherein the plurality of first peripheral transducers and the plurality of second peripheral transducers include at least one input transducer configured to operate only in a transmit mode by transmitting signals from the first surface to the second surface and at least one output transducer configured to operate only in a receive mode by receiving signals transmitted from the second surface to the first surface, wherein at least one of the plurality of second peripheral transducers is selectively steerable to communicate signals between the plurality of second peripheral transducers and multiple transducers of the plurality of first transducers, and wherein the first interior transducer includes an array of transducers that are each oriented to communicate with at least one of the plurality of second transducers; and transmitting a signal between at least one of the plurality of first transducers and the at least one second transducer without physically penetrating the electromagnetic barrier.
