Appel-Hansen

However, there were other important contributions. Hansen discussed the relationship between antennas as scatterers and as radiators [40]. Garbacz discussed measurement techniques [41], and so did Appel-Hansen [42], Wang et al. [43] and King [44]. Several oral papers about measurements were presented by Heidrich and Wiesbeck [45-48], culminating with the dissertation by Heidrich [49].
