Inverse scattering of dielectric cylinders by a cascaded TE-TM method

A novel approach for inverse scattering of dielectric objects is proposed. This reconstruction algorithm aims to synthesize individual TE and TM inver se scattering in order to decrease the effect of ill-posedness. The propose d synthesizing method has a cascade structure composed of TE and TM inverse scattering algorithms. Appropriate approaches are adopted in these two alg orithms to take advantage of the physical difference between them. A transm ission-receiving diversity scheme of multiple incident views and receiving points is also incorporated. Numerical simulations are conducted to compare the proposed synthesizing method with two other methods using individual T E or TM information. Some advantages of the synthesizing method are also ob served.
