Where Does Electromagnetic Interference Come From?

Is there any electronic product that can be called free from interference due to electric signals? 

Simply No!

What is this sound all about?

In simple language, the electric signals that interfere with the normal functioning of the electronic equipment are electromagnetic interference. Every electronic and electric system, equipment creates some signal, which can hinder the normal functioning of another piece of equipment nearby. Not just this, EMI can lessen the functioning of the equipment, lead to operational faults, and even complete failure.

Now, Where Does This EMI Comes From?

EMI can either be self-generated, due to interference between two circuits in the equipment or created externally by some other equipment or device in the same environment.

The earliest form of Electromagnetic Interference (EMI) and radio-frequency interference (RFI) comprised of spurious signals coming from radio transmitters that are disturbed by other radios. For instance, harmonics generated by band radios led to television interference.

An exponential rise in Electromagnetic Interference is expected to happen. It is because of the rising number of wireless devices, including cell phones, GPS, and Bluetooth.   However, digital equipment, interference caused by RF Sources, and computers has become a leading cause of EMI. 

Switch-more power supplies are also one of the leading causes of EMI generation. The rising use of microwave frequencies for digital and radio applications has contributed to more EMI.

Still, have concerns and questions?

Does your television function without getting interfered with by a Personal Computer?  The security system, won’t it get affected by radiation coming from any RF source nearby?  The interference in DSL with the telephone operation!

Mitigation of EMI

Management of Electromagnetic Interference has a list of solutions at both victim and emitter devices. Some of them can be raising the spacing between the victim and the source. It may also include physical orientation, such as rotating a device at 90 degrees.  However, the real solution for it can include the proper design of the equipment to reduce emissions or to make it less at risk to external EMI.  Different ways of reducing EMI can include grounding, filtering, and shielding.

Graphene Absorber for EMI Shielding 

Graphene absorber is a flexible, lightweight, and thin conductive sheet. It possesses superior thermal and electrical properties with structural integrity and mechanical flexibility. It is useful for dissipating heat and lessening problems connected with EMI. It is mechanically strong, resistant to corrosion, and extends processing advantages too. Graphene absorber sheets come in different thicknesses to meet the requirements for Electromagnetic Shielding applications.

About Silver Nanowires and Its Applications

  Silver Nanowires are nanomaterials with high electrical conductivity, resistance to oxidation, and great optical & antibacterial properties. Silver Nanowires also performs great in transparent conducting electrodes for touchscreens, solar cells, flexible displays, sensors, light-emitting diodes, etc. These nanowires can be included in many products like textiles, antibacterial bandages, and EMI shielding. Additionally, silver nanowires have been great as conductive fillers for combined applications. Now, it is essential that the minimum amount of silver is used for establishing the electrical connection in the final matrix, also known as the percolation threshold. Due to its high aspect ratio, silver nanowires can easily reach percolation at concentrations of less than 1%. With great electrical, optical, and thermal properties, silver nanowires have great possibilities for developing advanced technology applications. They are available in powder and dispersion form. The S...
