Does it take a lot of energy to make aluminum foil?

    Foil can produce about 100MHz, the eletric field is attenuated by more than 80 decibels (dB) (only 10(8)=0.00000001 of the energy gets through. A field traveling through one skin depth will lose about 63 percent of its energy (it is attenuated to (1/e) = (1/2.718…) of its original energy.
