P3.24. Source and more field variations from a given field variation of a uniform plane wave. The time variation of the electric-field intensity Ex in the z = 300 m plane of a uniform plane wave propagating away from an infinite plane current sheet of current density Js(t) = -Is(t)a, lying in the z = 0 plane in free space is given by the periodic function shown in Fig. 3.37. Find and sketch (a) Js ver- sus t; (b) Ex versus t in z = -600 m plane; (c) Ex versus z for t = 2 us; and (d) H, versus z for t = 3 us.
