Fig. 26.

Upper panels: a the y-component of the magnetic field, $B_{\mathrm{y}}$, with x-z electric field depicted by arrows, and b the x-component of the electron current density, $J_{\mathrm{x}}$, with the x-z magnetic field as arrows, both in the $x-z$ plane at $t=1000{\omega }_{\mathrm{pe}}^{-1}$. The lower panels show the total magnetic-field strength in the $y-z$ plane at $x/\Delta =700$ (c) and $x/\Delta =835$ (d). The arrows indicate the magnetic field ($B_{\mathrm{y}},B_{\mathrm{z}}$).
