Emi Shielding: Why And Where Is It Needed?

In simple words, it is the interference from an electrical or electronic system to another due to the electromagnetic field by the operations.

Electromagnetic Interference in Daily Life:

• The interruption in video or audio signals that you notice on video devices or radio, which happens due to an aircraft flying at a lower altitude.
• The unpleasant noise generated by the grinder in the kitchen or welding machine.
• The noise of microphones comes from a mobile phone shaking with a communication tower while processing a call.
• While boarding a flight, you have to switch off your phones. That is because EMI from active mobile phones intervenes with navigation skills. 

EMI Shielding: Why Is It Needed?

The advent of technology and its role in daily life has given a rise to electromagnetic interference. These signals come from different sources leading to major interference and can leave a negative impact on other unshielded components present in a device as well as the surrounding equipment. 

It can be a cause for different issues in an appliance, which can lead to weak performances and even permanent damage. When it comes to small-sized components with faster-operating speeds, it gets difficult to restrict the electromagnetic pollution caused by them. It calls for shielding to make sure that systems are operated safely. Thus, EMI Shielding is recommended to protect systems from any unintentional or intentional interference.

 EMI Shielding: In What Areas Are Did it need?

1. Automotive  

A new wave of electric vehicles, as well as autonomous cars, is being witnessed in the rapidly changing automotive industry. These vehicles come with advanced features, including touch screen systems, hands-free systems, onboard GPS navigation systems, and Bluetooth. The electronics in the automobile are becoming a challenge when it comes to facing Electromagnetic Interference. Thus, EMI shielding is of high demand in autonomous and electric vehicles in comparison to conventional cars.  

2. Telecommunications

With the rising adoption of smartphones and the launch of technologies such as 5G, the telecommunication industry has witnessed rapid growth. The components, as well as towers in use, require protection to make sure that smooth data is transferred to and by consumers. EMI shielding is needed in this area, and an increase shortly is expected to happen.  

3. Defense

EMI Shielding is one of the essential technologies in the field of the military. Its use in drones, control panels, helicopters, and trucks as a protective covering safeguards sensitive components. The quality of EMI shielding is essential to battle the disturbances.  

4. Aerospace

The continuous growth in the aerospace industry follows the need for the lessening of the susceptibility of the piece of equipment used in this field for Electromagnetic Interference. When such equipment faces interruption, it should not produce radiation to a stage that hinders operations. Thus, the application of EMI filtering material has risen in the aerospace industry.

Final Thoughts

Apart from the electronic gadgets and other areas, electromagnetic interference can leave an impact on the human body, which calls for EMI Shielding. However, the methods to opt for it depend upon the metal. Different researches have shown that graphene, owing to its excellent conductivity, is an ideal solution for such applications. It is flexible, corrosion-resistant, lightweight, and carries other processing advantages.

Graphene Absorber is a thin, lightweight, and flexible conductive sheet, which offers thermal and electrical properties along with its structural integrity and mechanical flexibility. This material can be relied upon for frittering away heat and then reducing problems associated with EMI. It possesses different advantages, including corrosion resistance and mechanical strength.
