Abstract
|
|
|---|---|
| In this work we propose a non-iterative method based on topological derivative computations to detect structural defects or inclusions (determine their location, size, shape, orientation) by combining multifrequency near?field observations of the total acoustic wave at a few obser- vation points. We will show some numerical tests illustrating the viability of this technique in different situations including the simultaneous reconstruction of objects of different sizes and the identification of poorly illuminated defects. | |
