Figure 7: Experimental setup.
Picture of the experimental microwave setup in the anechoic chamber of the CCRM and the two HRI spheres in both large- and small-gap cases (in the inset). The source has a fixed position; the receiver moves circularly around the spheres which are positioned on the central vertical polystyrene mast. The scattered field measurement is performed in the horizontal scattering plane containing the source, the receiver and the target (spheres). The configuration in the photograph corresponds to the perpendicular polarization (IS) case, here the transverse polarization configuration. The parallel polarization (IP) case, here the longitudinal configuration, is obtained by rotating the source and the receiver.
