Figure 9

FEM results showing the decreased insensitivity caused by the fringe effect. The black line is the normalized sensitivity of the plane-parallel capacitor from an ideal model. The green line is the normalized sensitivity of the area-changed capacitance considering the fringe effect. The red line is the influence of the fringe effect (Ke), defined by the value of the points on the green line divided by the points on the black line.
