The graph on the top plots the absolute value of V-tilde of d along the vertical axis, ranging from 0 to 1.4 V in increments of 0.2, and also plots d along the horizontal axis, ranging from lambda to lambda over 4 in decrements of lambda over 4. A cosine wave is plotted between the maximum value of 1.3 V and the minimum value of 0.7 V, with the corresponding d sub max and d sub min values marked to the left of lambda over 4 and to the left of 0, respectively.

The graph on the bottom plots the absolute value of I-tilde of z along the vertical axis, ranging from 0 to 30 m A in increments of 5, and also plots d along the horizontal axis as in the first graph. A sinusoidal wave is plotted between the maximum value of 26 m A and the minimum value of 14.5 m A. The maximum value of current corresponds to the minimum value of voltage, and vice-versa.
