Assumed gain and phase characteristics of the WPT-Pre (DC) and EFD systems. From the top, gain, phase, and phase delay curves are shown in the frequency range of 1–256 Hz. Black lines indicate the differential electric field channels (E u and E v), which include the low-pass filter with a cutoff frequency of 100 Hz. Blue lines indicate the potential channels (V u1, V u2, V v1, and V v2), which directly reflect the characteristics of WPT-Pre (DC). The thick and thin lines indicate plasma resistance of ~ 10 and ~ 100 MΩ, respectively. Normal and dashed lines indicate the WPT-Pre (AC) H-gain and L-gain, respectively
