Equivalent of a "ground" boundary at infinity ?

Hello everybody,
i'm actually using COMSOL v3.5a with AC/DC module to simulate how go electric fields and associated forces in various kind of solutions at nanoscale but i get one main problem.
I'm trying to simulate the electric field generated by a charge pattern at the surface of a 100nm PMMA (polymer) layer once immersed in a hexane solution.
The system/geometry is quite easy (see joined document) but the major issue is that i need to put some boundary to the ground to get a solution returned by COMSOL. Of course, depending on the way i define the ground boundary, my electric field lines change a lot. Furthermore, normally and physically speaking, the ground is "ad infinitum".
I hope you will have a few minutes to have a look on my model and give me advices about this.
Thanks in advance for your attention,
Etienne
