## Homework Statement

Plane monochromatic waves are propagating in free space parallel to the x-axis

in both positive and negative directions. At the origin the field strengths are

given by:

Ez = E0 cos wt Ey = 3E0 cos wt

cBz = E0 cos wt cBy = E0 cos wt

Find the amplitudes and polarisations of the forward and backward travelling

waves, and the net energy flux

## The Attempt at a Solution

I only get the backward amplitude which is 2E0 parallel to y-axis and the net flux which is E0^2/Z0

Can anyone help to find the forward amplitude?
