A Mathematical and Deterministic Analysis of the Time-Reversal Mirror
نویسنده
چکیده
We give a mathematical analysis of the “time-reversal mirror”, in what concerns phenomena described by the genuine acoustic equation with Dirichlet or impedance boundary conditions. An ideal situation is first considered, followed by the boundary-data, impedance and internal time-reversal methods. We explore the relationship between local decay of energy and accuracy of the method, and explain the positive effect of ergodicity.

A Numerical Investigation of the Time Reversal Mirror Technique for Trans-skull Brain Cancer Ultrasound Surgery
Introduction: The medical applications of ultrasound on human brain are highly limited by the phase and amplitude aberrations induced by the heterogeneities of the skull. However, it has been shown that time reversing coupled with amplitude compensation can overcome these aberrations. In this work, a model for 2D simulation of the time reversal mirror technique is proposed to study the possibil...

The study of many scientific and natural phenomena in laboratory condition is sometimes impossible, therefore theire expresed by mathemathical models and simulated by complex computer models (codes). Running a computer model with different inputs is called a computer expriment. Statistical issues allocated a wide range of applications for computer expriment to itself. In this paper, ...
متن کاملNumerical Simulation of Acoustic Time Reversal Mirrors
We study the time reversal phenomenon in a homogeneous and non-dissipative medium containing sound-hard obstacles. We propose two mathematical models of time reversal mirrors in the frequency domain. The first one takes into account the interactions between the mirror and the obstacles. The second one provides an approximation of these interactions. We prove, in both cases, that the time revers...
متن کاملOptimization of time reversal focusing through deconvolution
In this study a technique is demonstrated to optimize the ability of time reversal to both spatially and temporally focus, or compress, elastic wave energy. This method allows for optimization of time reversal focusing for any number of channels by calculating the required time reversed signal to be rebroadcast from the time reversal mirror element using only the original recorded scattered sig...
متن کاملA time - reversal method for an acoustical pulse
In the recent years a considerable amount of mathematical work have been devoted to the study of reeected signals obtained by the propagation of pulses in randomly layered media. We refer to 1] for an extensive survey and applications to inverse problems. The analysis is based on separation of scales between the correlation scale of the inhomogeneities present in the medium, the typical wavelen...
