A shielding enclosure needs to be a few skin depths in thickness at the required frequency and any holes in the cage need to be small compared with the wavelength. Even a narrow slit like a knife cut will allow waves to enter unhindered.obider77 said:So i have learned about the ability of Faraday Cage for blocking an external electric field. But is the thickness of the conductor effect the ability? Is there any limit of its thickness so that the cage won't be able to block external electric field anymore? I have read and searched about this topic but i haven't found anything for this, mostly i found about Faraday Cage ability to block electromagnetic wave. Can anyone please help? Thank you
I guess you are talking about blocking an electromagnetic wave, not electric field itselftech99 said:A shielding enclosure needs to be a few skin depths in thickness at the required frequency and any holes in the cage need to be small compared with the wavelength.

A Faraday Cage is a structure made of conductive material, such as metal, that is designed to block external electric fields. It works by distributing the electric charge evenly on the outer surface of the cage, thus canceling out any electric fields inside the cage.
A Faraday Cage works by creating a barrier between the external electric fields and the objects inside the cage. The conductive material of the cage absorbs and distributes the electric fields, preventing them from passing through and potentially damaging the objects inside.
The thickness of the conductor needed for a Faraday Cage depends on the strength of the electric fields it needs to block. Generally, a thicker conductor will provide better protection against stronger electric fields.
No, thicker conductor is not always better for a Faraday Cage. While a thicker conductor can provide better protection against stronger electric fields, it also increases the weight and cost of the cage. In some cases, a thinner conductor with a higher conductivity may be just as effective.
Yes, besides the strength of the electric fields, other factors to consider when choosing the thickness of the conductor for a Faraday Cage include the size and shape of the cage, the type of material used, and the frequency of the electric fields. It is important to carefully consider all of these factors to ensure the most effective protection against electric fields.
