Aluminum foil for electromagnetic shielding
The shielding effectiveness of aluminium foil roll depends upon the type of incident field (electric, magnetic, or plane wave), the thickness of the foil, and the frequency (which determines the skin depth). Shielding effectiveness is usually broken down into a reflection loss (the energy bounces off the shield rather than penetrates it) and an absorption loss (the energy is dissipated within the shield). Aluminum foil for electromagnetic shielding : Excellent High Frequency RF Shielding characteristics Effective barrier against Low Frequency AC Electric Fields when grounded. Electrically Conductive Weather Resistant Can be used as a Vapor Barrier – not breathable Heavy Duty / Tear Proof Flexible and light weight which allows for an easy installation Safe to handle and non-toxic Although aluminium is non-magnetic, it is a good conductor, so even a thin sheet reflects almost all of an incident electric wave. At frequencies more than 100 MHz, the transmitte...
