  • Tuned wave phased array
    Patent number: 6728515
    Abstract: A tuned wave phased array includes a plurality of spaced transmitter elements, a signal generator that produces an activation signal for activating the transmitter elements to transmit a guided wave in an associated medium and a delay circuit for sequentially delaying the activation of at least one of the transmitter elements for creating constructive interference of a selected mode of the wave propagating in the medium, thereby boosting the selected mode of the wave.
