WebYes, stainless steel wire mesh can be an effective material for EMI and RFI shielding. Like copper wire mesh, stainless steel wire mesh is highly conductive and can block or absorb electromagnetic radiation. Moreover, stainless steel wire mesh has a high nickel content, which provides excellent corrosion resistance and durability. WebJan 3, 2013 · The resonant frequency is the frequency where integer half-wavelengths correspond to the dimension of the shielding enclosure. A wave is set up inside the enclosure whose nodes (i.e., zero amplitude) lie on the conductive walls of the enclosure. These structures behave as cavity resonators.
