(TU Delft Applied Geophysics and Petrophysics) van der Neut, J.R. (TU Delft ImPhys/Acoustical Wavefield Imaging) van Dongen, K.W.A. (TU Delft ImPhys/Acoustical Wavefield Imaging) Wapenaar, C.P.A. (TU Delft ImPhys/Medical Imaging; TU Delft Applied Geophysics and Petrophysics) Date 2019 Abstract Wavefield focusing can be achieved by Time-Reversal Mirrors, which involve in- and output signals that are infinite in time and waves propagating through the entire medium. Here, an alternative solution for wavefield focusing is presented. This solution is based on a new integral representation where in- and output signals are finite in time, and where the energy of the waves propagating in the layer embedding the focal point is reduced. We explore the potential of the proposed method with numerical experiments involving a 1D example and a cranium model consisting of a skull enclosing a brain.
