Frequency dependence of complex NLC components. Top panel Plot of fitted Q_max of 2-state components of complex NLC. The real and imaginary component magnitudes intersect at a particular frequency, F_is. Here the imaginary component absolute magnitude is plotted. Fits (solid lines) are with Eq. (2). Red is real component; blue is imaginary component. F_is is 18.5 kHz. Middle panel Plot of the Boltzmann parameter, z. Both decrease in parallel with frequency, with the imaginary component being smaller, indicating a shallower voltage sensitivity. Bottom panel Plot of difference between real and imaginary ΔC_sa, showing some low frequency dependence. Figure 1A,B indicate that ΔC_sa is largely absent in the imaginary component.
