E2=getelectric("monitor");

or

E2=E.E2;

Or 

E2=abs(Ex)^2+abs(Ey)^2+abs(Ez)^2;

as long as you get E dataset using getresult("monitor","E");

Please note that, your monitor is a 2D monitor, so its data is spaially distributed. If you are sure it is a plane wave, you can use any point 's E to reprent the plane wave. Otherwise you will need 2D data in physics.
