Frequency dependence on image reconstruction for a buried imperfectly conducting cylinder is investigated. A conducting cylinder of unknown shape and conductivity is buried in one half‐space and the incident wave is scattered from another half‐space. By using measured scattered field, the image problem is reformulated into an optimization problem and solved by the genetic algorithm. Frequency dependence on image reconstruction is investigated and numerical results show that the reconstruction is well in the resonant frequency range. On the contrary, if the frequency is too high or too low, then the reconstruction becomes bad. This work provides both comparative and quantitative information. © 2002 Wiley Periodicals, Inc.
