Most microwave inverse scattering algorithms developed are for transverse magnetic (TM) wave illumination in which vector problem can be simplified to a scalar one, which less works have been reported on the more complicated TE case. In the TE case, the presence of polarization charges makes the inverse problem more nonlinear. This paper uses the self-adaptive dynamic differential evolution (SADDE) algorithm to recover the shapes of the two dimensional conducting cylinders by TE plane wave illumination. Based on the boundary condition and the measured scattered field, a set of nonlinear integral equation is derived and th
