Terahertz Radiation from a Plasma Cylinder with External Radial Electric and Axial Magnetic Fields

Figure 3

Snapshots of the current distribution at (a) 11.72, (b)13.18, (c) 14.65, and (d) 16.11 ps. The black arrows represent local current vectors. Close inspection shows that the currents oscillate both radially and azimuthally. The white dashed circles mark the boundary of the initial plasma cylinder.
