Abstract :
This paper presents an analysis of the measurements of the electromagnetic scattering in open field at the frequency of 8.76 GHz through the radar cross section (RCS) in the bi-static condition. Three structures have been investigated: a plane plate, a dihedral angle of 95°, and a metallic massive cylinder, in all cases before and after application of the multilayer absorbing material. The RCS measurements were performed with the plate and the effective area of the dihedral angle orthogonal to the propagation vector of the incident wave and the axis of cylinder parallel to the same vector. The obtained results were compared and analyzed so as to make possible to estimate the efficacy of the electromagnetic radiation absorbing material (RAM) in plane and cylindrical structures.
