Fig 2. Electric pulse generation and shape.

Fig 2

A: Pulse generation with a transmission line generator. Rcharge is the charging resistor, Ztl is the impedance of the transmission line, Ztissue is the impedance of the tissue, and Zm is the additional impedance added in parallel to the tissue in order to match the impedance of the load to that of the transmission line. VBD is the breakdown voltage of the spark gap, adjustable by changing its width and L is the length of the transmission line. B: Theoretical pulse shape, for the diagram in Panel A, where v is the speed of light in the transmission line. Pulse duration is proportional to the length of the transmission line in Panel A. C: Experimentally measured pulse shape.
