I have a Faraday cage and inside there is a WIFI router whose RF I am trying to contain. The cage is made of aluminium mesh with hole sizes of 3 mm or so.
What happens to the RF electricity coming from the RF WIFI router and hitting the Faraday cage (from inside) if I don't ground the cage?
Would the electricity "build up" inside/on the cage and in what form since it will cease to be RF?
I have had the RF WIFI router emitting for few hours however I cannot detect any voltage increase on the cage's surface.
I measured for DC and AC using a multimeter and the values remain constantly the same - about 4 volts AC.
