✦ Synopsis

In this letter, a new method for reconstructing the bound of impenetrable two-dimensional objects is presented. From a set of measurements in the near-or far-field region, we calculate the coefficients of multipolar equi¨alent sources located inside the unknown object. Thus, the shape of the object is obtained through the constraint of the tangential electric field boundary condition. Numerical simulations for TM polarization problems are presented to demonstrate the accuracy of the proposed method.
