Abstract:
1. A transducer array apparatus comprising: a plurality of array elements, each of said array elements including a transducer-oscillator pair wherein a transducer is operably coupled to a nonlinear oscillator, said transducer-oscillator pairs contributing to generating a beam pattern for receiving or radiating a signal; coupling means for interactively connecting said transducer-oscillator pairs, wherein said coupling means is characterized by a coupling strength factor, a coupling phase, and by a coupling topology; wherein each said nonlinear oscillator is characterized by an oscillator frequency and by an oscillator amplitude, means for adjusting said oscillator frequencies so that said beam pattern is steerable in direction; and means for adjusting said oscillator amplitudes so that said beam pattern is adjustable in amplitude.
