This question already has an answer here:
I have created a faraday cage with metal sheet of .5 mm thickness with aluminum foil wrapped outside and inside of the cage. I was happy at first to notice that the cellphone signal goes from one bar to nothing at all but the signal goes inside the cage intermittently and most of time stays at full strenght signal. I tried changing places and found dead zones but still frequencies go inside. Wifi signal though still cannot be attenuated. I was planning to create a topological shielding with 10x sheet of 1 mm and layer them together to deplete the frequency but i cant afford to do it if i plan to stay inside longer because of temperature issues. The reason I am doing this is because of electronic harrasment. I researched that devices can be hacked through emf emissions of devices and i need to protect my devices from these attacks.
My question is,
is there by any chance that the signals inside can be cancelled consistently?
Do i need to consider the thickness of metal sheet or do i need to just layer tin foils to be enough to reflect or absorb frequencies.
Do i need to make earth stakes to transfer the electrons on the metal to earth to regain it's absorption and reflection?
Do i need to create topological shielding to deplete the frequecy from GHz to MHz brcause i researched that cellhpone signals are on a MHz frequency?.
I found out as well that apperture/ appertures should be smaller than the wave.
I need your help thank you.
