Electromagnetic imaging of lossless dielectric cylinder using confined iterative method

The inverse problem of reconstruction the permittivity distribution image of a lossless dielectric cylinder from scattered electric field is discussed. The discretization inverse scatter problem involves of very nonlinearity and ill-pose. Due to the high numerical complexity, the proposed method is based on the BIM (Born iterative method), joining the confined condition to the solution. This method descends the permittivity distribution errors and enhances the image accuracy in comparison with BIM. From the simulation data, some numerical results of image reconstruction are given to show the efficiency of the proposed method for image reconstruction.
