To better understand power absorption by the pickup (Pu) electrode, we calculated the characteristic impedances and sensitivities in both sum and difference modes for the 1-2 GHz and 2-4 GHz Pu electrodes. Since the design for the 1-2 GHz system essentially has been settled, our investigations are of more importance for the 2-4 GHz design which has not been finalized. One main feature of our results is that sum (ZΣ) and difference (ZΔ) mode impedances are not equal, as is often assumed.
