You've neglected some very important points in your shielding attempt.
For best effectiveness, you have to match the *current diverting path*
impedance to the sheet impedance of the aluminium foil.
Shit impedance is given by R/square = Rho/thickness. Then substract the
conjugate of the ground impedance, and you'll have your target for the link
Oh, one more point : aluminium foil often have one matt side, one shiny
side. It is very important that you put the matt side inside. Please believe
me, it's very important.
