Electric Field in an object place in an EM field

Hi,

I am quite new to COMSOL and with some help from tutorials I have built this 3D model where a cylinder is placed in the electric field radiated by a dipole antenna.

To calculate the Electric field in the cylinder is it enough if I just included boundaries of the cylinder in the far field calculation physics??

And also is there a way to export the Electric field data only from the cylinder???

I am not able to attach the file at it is too big....
