Abstract: A efficient inversion is proposed by using domain decomposition based IE modeling with incorporating the pure contrast source inversion (DDIE-CSI) for complex structures Firstly, a new rule is defined according to an induction coefficient with the topographic relief situation With the reference model, background medium and the distribution of target body medium area, then the computational domain consisting of the target body, background medium and complex structure is decomposed Gaussian filtering based Anderson’s algorithm is used to calculate the primary field from the excited sources The stable double conjugate gradient-fast Fourier transform incorporated based integral equation algorithm is applied to obtain the complex structure electromagnetic responses fast Then DDIE-CSI is applied to some 25D imaging problems with complex terrain The efficiency of the new algorithm is demonstrated by comparing with the published results of 3D boundary integral equation Finally, the imaging results and the electromagnetic field response of complex structure under the surface and well electromagnetic observation systems are analyzed
