A sheet of current lies in the xz plane as shown. A surface current K is applied along the z axis which alternates sinusoidally at a frequency f.

2. A sheet of current lies in the xz plane as shown. A surface current K is applied along the z axis which alternates sinusoidally at a frequency f. i.e. K=K0sin(2(pi)ft)Consider regions close to the surface where the plane of current appears of infinite extent. Plane electromagnetic waves travel away from the sheet in both the positive and negative y directions.(a) In what axis will be the electric field vector?
