EMI Shielding

EMI Shielding or Electromagnetic shielding is the practice of reducing and redirecting electromagnetic fields (EMF) typically in a confined area or space with barriers made of magnetic or conductive products and materials. These unique products and materials are often applied to electronic boxes, cabinets, and enclosures, for isolating a variety of electrical equipment and devices from their surroundings. The objective with these shielding products and materials is to reduce electromagnetic interference (EMI) through the coupling of radio waves, electromagnetic fields, and electrostatic fields in a specific application or environment.

As electronic devices operate, they emit electromagnetic radiation which crosses the path of other devices and sometimes the devices themself, interfering with operation.

What is the Purpose of EMI Shielding?

Understanding antennas and electromagnetic fields is the first step to understanding EMI shielding. EMI shielding is important for achieving electromagnetic-compatibility (EMC) for electronic products including digital systems. 

EMI Shielding is a tactical effort within EMC design strategy to: 

  1. eliminate external sources of electromagnetic radiation
  2. prevent electronic devices from interfering with its own operation (crosstalk) 
  3. reduce electromagnetic radiation that may interfere with other electronic equipment and systems when operating in a specific  environment.
  4. keep circuits from misbehaving as a result of ambient EMI/RFI from communication towers, aircraft, radio stations, etc…


Who Needs to Care About EMI Shielding and EMC Design?

Electronic equipment is used everywhere, often without any problem at all, however, there are several industries where it is critical to account for and strive for optimal function of electronic equipment.  To make it even more complicated, with digital systems’ ever-increasing frequencies and edge rates, EMC is becoming harder to achieve. Where might EMI Shielding be critical?

In these industries, electronic devices might need to operate with high levels of security to protect data transmission as well as ensure fail-proof functionality. EMI shielding could mean the difference between leaked military secrets, medical equipment failure, disruption to public utilities access like water, electricity and gas, as well as disruption to cell, internet and other communications services.

majr products emi shielding signals securedHow Do You Shield Against EMI?

In the simplest terms, the goal is to block  transmission and/or emission from devices. Depending on the device, its purpose, the potential for interference and its environment, EMI Shielding is typically comprised of a product placed on, in, or between a device or its enclosure. 

Examples of where and how EMI shielding is implemented include:
