Dear Sirs,give me an advice about how to connect 3 finite ground layers, please.

I have a structure with 3 finite ground layers. According to the IE3D User's manual, to have a finite ground layer, in basic parameters

I changed No. 0 G (infinite perfect ground) substrate layer to dielectric layer.

Next steps are drawing, in polygon editor, a polygon at Z=0 (first ground layer) and other 2 ground layers at different Z.

How can I set the simulator to interpret these 3 layers as 3 finite ground layers?

I have to connect these 3 layers with vias?

Thanks for your reply.
