"The time reversal mirror (TRM) is a method which can be effective in NDE of defects in materials. In this case an input ultrasonic wave is transmitted into the examined sample, then recorded by receiving transducers, time reversed and sent back by the same transducers. A simple numerical model of a solid plate was developed. Using this model, a simulation of TRM was performed. The propagation of ultrasonic waves used in time reversal method is studied. A number of tests with various configurations of transducers and defects and different methodology of the TRM procedure is simulated."@en . . . "P(GA103/06/1711), P(GA106/07/1393), Z(AV0Z20760514)" .
