Abstract
The Time Reversed Acoustic (TRA) focusing technique based on acoustic reverberated media provides an elegant possibility of both temporal and spatial concentrating of acoustic energy in enclosure. The TRA focusing techniques were carried out for the basic simulation. A method of prediction of the TRA focused ultrasound waveforms and spatial distribution using the simulations of impulse response relating the signal at the TRA transmitter to that at the any tested point has been developed. The TRA focusing process is simulated and analyzed using multiple sources in two-dimensional rectangular enclosure. In this study, we get first the extraction of the impulse response signal from the sound reflection simulation in the rectangular enclosure and then the TRA focusing is performed. From these simulations, as well as a ultrasonic field related to health care and acoustic communication technology the TRA focusing technology is expected to be applied.
