The ability to reduce electromagnetic (EM) radiation in a space by blocking the field with barriers of conductive or magnetic materials is called electromagnetic interference (EMI) shielding. The ever-increasing production of smart electronic devices and wireless communication systems such as radar, wireless network, Bluetooth, radio and TV transmission, EM missiles, aviation, satellite communication, global positioning systems (GPS) and remote controls in the developing world technology The age of artificial intelligence is the primary cause of EM pollution. are resources.
The shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields (EM shielding that blocks radio frequency electromagnetic radiation is also known as RF shielding). The amount of reduction depends heavily upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an electromagnetic field.
EMI shielding methods traditionally rely on metal, which adds weight and is expensive. Significant graphene-based materials can outperform conventional metal shielding due to their light weight, resistance to corrosion, flexibility, and processing advantages. On top of all these, graphene's excellent conductivity makes it a perfect candidate for electromagnetic applications such as EMI shielding, radar absorbing etc..
