Electromagnetic Shielding Section COULD be Misleading
The article states that "At frequencies more than 100 MHz, the electric field is attenuated by more than 80 decibels (dB) (less than 10−8 = 0.00000001 of the power gets through)." That is, it creates the impression that ALL frequencies above 100 MHz will be attenuated to a high level. I have only my basic experimental observations to go from BUT I have reason to believe that some frequencies above 100 MHz will not be attenuated - essentially creating 'Frequency Windows', which I imagine may be a general feature for many materials, through which Electromagnetic Interference will penetrate a Faraday Cage constructed out of Aluminium Foil. Am I mistaken? ASavantDude (talk) 20:12, 5 January 2018 (UTC)
