摘要：
The reconstruction of inclusions is an important problem in engineering from the knowledge of the time harmonic incident electromagnetic wave and the far-field or near-field of the scattered wave with frequency in the resonance region. In the paper, the development of various well-known methods since 1986 is briefly reviewed, the two-dimensional Helmholtz equation, taking into account cylindrical bodies, is studied. An integral equation is established by Green's formulation for inverse obstacle scattering considering both the interior and the exterior problems of the Helmholtz equation, the existence, uniqueness and solvability of the integral equation are given. Some numerical examples are given showing its practicality and feasibility.
