Image reconstruction for a perfectly conducting cylinder buried in a three-layer structure by TE wave illumination

The imaging of a perfectly conducting cylinder illuminated by transverse electric (TE) wave illumination is investigated. A perfectly conducting cylinder of unknown shape buried in the second layer scatters the incident wave from the first layer or the third layer. The metallic cylinder, with cross section described by an equation, is illuminated by an incident plane wave whose magnetic field vector is perpendicular to the z axis (i.e., TE polarization). Based on the boundary condition and the recorded scattered field, a set of nonlinear integral equations is derived and the imaging problem is reformulated into an optimization problem using a genetic algorithm.
