An example data set of transmission intensity vs. applied voltage showing a saturation in transmission intensity. The maximum applied voltage is 140 V. V(z, f ) / V0 Supplemental Fig. 2. Surface plot of the calculated electric potential as a function of frequency and position along the length of a 40-cm long fiber contacted at the 0-cm side. The geometry used for this calculation is the same as in Fig. 3(a) of the manuscript; the resistivity of the CPE electrodes (1.1 Ωm) is replaced by the resistivity Bi58Sn42 ((39*10-8 Ωm)). At a driving frequency of 1 kHz or lower, the electric potential is the same along the entire fiber length.
