摘要A computational method combining the genetic algorithm (GA) and atwo-phase technique is reported for electromagnetic imaging of ahomogeneous and/or multiple cylinders of arbitrary shape. Thestructure can consist of dielectric and metallic objectssimultaneously. By measuring the scattered field, the shape, location,size and permittivity of the object are retrieved quite successfullywithout any prior information. The forward problem is solved based onthe equivalent source current and the method of moments (MoM), whilethe inverse problem is reformulated into an optimization one, and issolved by the proposed scheme. Numerical simulation shows that goodreconstruction can be obtained, and the computational time can bereduced efficiently by the proposed two-phase technique.
