Antenna array consists of two infinite plane parallel sheets in the xy plane spaced half a wavelength apart and having current densities. Wave is propagating in vacuum.

[tex]J_{s1} = J_{so}cos(\omega t) \vec{i} [/tex] z = 0

[tex]J_{s2} = J_{so}sin(\omega t) \vec{i} [/tex] [tex]z = \frac{\lambda}{2}[/tex]

The time average of the Poynting vector is required to e 500 W/m^2 to the right of second antenna ([tex]z > \frac{\lambda}{2}[/tex] )

I have to find surface current Jso is needed?

I think that I have to find total E = E1 + E2 and then H. Poynting vector is given but I don't know how to surface current Jso from that. Any suggestions. Thanks
