(a) VDDOT signal detected by the D-Dot probe in shot #29; (b) time-gated normalized spectrogram of the signal; (c) recovered component of the electric field normal to the D-Dot ground plane. Time intervals a-f identified in (c) are discussed in more detail in the main text. In this Figure and in the next Fig. 4 the origin of the time scale was set at the moment when the EMP signal reaches the D-Dot probe.
