    I wanna add faraday cage in my PCB.But my PCB has 2 layer.I used Top Layer(Red) for GND Plane.I used Bottom Layer(Blue) for Power and Data traces.

    My Questions:

    1-) If i create GND Plane on Bottom Layer(Blue) and add vias at around PCB.Is there any objection? (Look undermost image)

    I don't think it will be very effective unless it totally encloses the circuit to be shielded. I expect you would need a multi-layer board to do that. These are just gut feelings; I haven't worked with Faraday cages or heavy duty PCB shielding before.

    Try asking in a forum related to PCB layout design. Here are two forums related to the Eagle PCB CAD package:
