Abstract

With the development of magnetic induction tomography, ground penetration imaging, and other noninvasive detecting applications, the need for a robust and fast inverse method becomes more and more urgent. In this paper, we develop a fast full-wave inverse scheme combined with a domain decomposition method (DDM). In this inverse scheme, the object domain, whose parameters are unknown, is separated from the peripheral devices and outer boundaries, and a regularized Gauss-Newton method is introduced to take control of the whole inverse iteration process, in which only the object domain has to be recalculated. This nonlinear inverse scheme is implemented successfully for 3-D full-wave problems and achieved a significant reduction of required computational costs.
