<p>A tuned wave phased array (10) includes a plurality of spaced transmitter elements (28a-28d), a signal generator (22) that produces an activation signal for activating the transmitter elements (28a-28d) to transmit a guided wave in an associated medium (20) and a delay circuit (24a-24d) for sequentially delaying the activation of at least one of the transmitter elements (28a-28d) for creating constructive interference of a selected mode wave propagating in the medium (20), thereby boosting the selected mode of the wave.</p> |
