We use infinitely many Cauchy data as measurement and give a reconstructive method to localize the interface. We will base this multiwave version of the no-response test on two different proofs. The first one contains a pointwise estimate as used by the singular sources method. The second one is built on an energy (or an integral) estimate which is the basis of the probe method. As a conclusion of this, the no response can be seen as a unified framework for the probe and the singular sources method. As a further contribution, we provide a formula to reconstruct the values of the jump of (x), x โ @D at the boundary.2004engdepartmental bulletin paperVoRhttps://doi.org/10.14943/83825http://hdl.handle.net/2115/6947910.14943/83825Hokkaido University Preprint Series in Mathematics674121https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/69479/1/pre674.pdfapplication/pdf200.14 KB2004
