Description:
Author(s): Tianci Cui, Theodor S. Becker, Dirk-Jan van Manen, James E. Rickett, and Ivan Vasconcelos In acoustics, the method of M a r c h e n k o r e d a t u m i n g , which can focus wave fields in an unknown lossless medium accessible from one side only, is powerful in helping to characterize a medium’s properties accurately and efficiently. Ubiquitous dissipation of wave energy challenges the method’s practical application, though. The authors develop the dissipative Marchenko method, which overcomes the lossless-medium assumption by numerically constructing a corresponding effectual medium from the double-sided scattering data measured from the actual lossy medium. This method will impact resource exploration, medical imaging, and nondestructive testing, among other fields. [Phys. Rev. Applied 10, 044022] Published Mon Oct 08, 2018
