Sažetak
In the paper it is shown how the absorption cross section of a lossy sphere and a lossy cylinder can be calculated from the scattered far field by using the forward scattering theorem and a moment method code. The results are in agreement with mean absorption cross section of a lossy cylinder found from the measured mean transfer level of a reverberation chamber used for measuring small antennas close to the cylinder. The formula that relates the net average transfer level of a reverberation chamber to the mean absorption cross section of a lossy object in the chamber has been published by Hill et al., so the present results represent a validation of their formula.
