Effect of increasing the electric field at a fixed applied frequency, i.e., 80 kHz, on the normalized pixel intensity as a function of time. Above 500 kV∕m, the partial resuspension and shifting of the stagnation point occurs as indicated by the dip in the normalized pixel intensity at about 200 s. Once the shift occurs, RBC trapping resumes at the new location as indicated by the reincrease in the pixel intensity at approximately 260 s.
