“…In this work we consider an alternative approach to the inverse source problem which, in some sense, is in the spirt of several recently proposed hybrid imaging modalities [3,6,11,20,26,31,37]. In these methods, a wavefield is used to control the material properties of a medium of interest, which is then probed by a second wavefield [6,7,4,14,12,13,35,27,24,15,29,30]. Here we exploit the acoustoelectric effect, in which the density of charge carriers and conductivity are spatially modulated by an acoustic wave [28,33].…”
