Figure 8.
Measured electric field E and estimated neural depolarization ∆Vm of (a) positive and (b) negative 25 μs monophasic pulse with an 8.5 μs interphase, and (c) positive and negative (d) 50 μs biphasic pulse with 8.5 μs interphases for with VCref = 1100 V. The interphases cause the coil current to be approximately trapezoidal.
