| 摘要 | A computational method combining the genetic algorithm (GA) and shape mutation is reported for electromagnetic imaging of a homogeneous cylinder of arbitrary shape. By measuring the scattered field, the shape location, size, and permittivity of the object are retrieved quite successfully. The forward problem is solved based on the equivalent source current and the method of moments (MoM), while the inverse problem is reformulated into an optimization one, and is solved by the proposed scheme. Numerical simulation shows that, even with a bad initial guess, good reconstruction can be obtained for a hollow object or multiple-cylinder object as long as the noise level is ≤−20 dB. |
