Radio - Frequency Electromagnetic Field Strength 50Mz – 3.5GHz. The conductive paint is an older technology. The interior of the enclosure is coated with a nickel filled acrylic paint.
Electromagnetic compatibility EMI/RFI shielding products are designed to either keep out or keep in electromagnetic interference. Shielding reflects and absorbs incident radiation. The higher the attenuation of the shielding, the more effective it is at keeping in or out the undesired electromagnetic interference.
World of smart technology, everything is turning wireless and requires electromagnetic shielding to protect the electronics within, or the people using them, from emissions. Cell phones, WiFi, cordless phones, are just a few of the technologies widespread today, which beam data through the air, instead of over a wire.
Low frequencies require the use of a magnetic material. ( < 100 MHz ) Mid frequencies will “re-radiate” from any conductive source. ( 30–300 MHz ) High frequencies will travel through the smallest openings. ( > 300 MHz ) An enclosure will “Absorb”, “Reflect”, and “Transmit” a certain percentage of the radiation beamed at it. The measurement of Attenuation is in dB, a logarithmic ratio of the drop in signal strength, example: 3 dB = 50 % 20 dB = 90 % 40 dB = 99 % 60 dB = 99.9 %
