The location results of the CAN model with its center coordinate oCAN at (a) (–20, 0) mm, (b) (–10, 0) mm, (c) (0, 0) mm, (d) (10, 0) mm, and (e) (20, 0) mm respectively. In each case, the moment t k i (i = 1 – 5) is determined when the maximum of the sum amplitude of P1 and P2, E MAX i , occurs. The distribution of P1 and P2 at that moment is plotted and the values are normalized by E MAX i .
