Abstract: Numerical computation of bistatic RCS is carried out by moment method for some infinite long cylinders filled with large loss dielectric (LLD) used in radar anti-stealthy technology and design of microwave dark rooms, in case of TM incident of wave. The simulation shows that the scattering is weak for materials with large permittivity and low loss. The electromagnetic parameters of filled dielectric have obvious effect on the scattering of the cylinders when ka0 is small, however, the effect becomes weaker with the increase of the angle between the cylinder to the two stations. When ka0 is large, the influence of electromagnetic parameters of the filled dielectric to RCS is weak, while the scattering energy gradually concentrates to the backward direction.

Key words: large loss dielectric(LLD), radar cross-section (RCS), moment method (MOM)
