Demystifying the World of Electromagnetism and EMC Testing

To illustrate the concept of Electromagnetism, let's consider the analogy of people living in the same apartment, engaging in various activities. For peaceful cohabitation, it is important to follow some rules. These rules include keeping noise down, not blasting music to avoid bothering others, respecting each other's stuff and personal space, and keeping common areas clean. Additionally, adding soundproofing to the place to block outside noise.

Similarly, electronic and electrical components must operate without causing or being affected by electromagnetic disturbances. This precaution ensures they do not interfere with the functioning of nearby devices and can withstand disturbances from their environment.

The Rising Importance of Electromagnetism

As we look towards the future with increased connectivity and an all-electric era, EMC becomes a critical discipline for ensuring the compatibility and robustness of our evolving technologies.

Armel Sangono who has just joined Cebi Testing Services as an EMC expert, emphasized the growing importance of electromagnetism in today's technologically advanced world. From his perspective, "The ongoing miniaturization and integration of electronic devices, alongside advances in wireless technology in sectors such as real estate, construction, aeronautics and automotive, highlight the dependency on electromagnetism. As modernism pushes the boundaries of what is possible, the exploration and application of electromagnetism will continue to be a driving force behind innovation, shaping the future of our society and global economy.

EMC Cebi Testing Services Utilization

Compliance with EMC regulations is crucial for several reasons:

EMC compliance is a fundamental aspect of product design and quality that affects functionality, safety, marketability, and innovation in the electronics industry.

  • Functionality: without proper EMC precautions, some devices could malfunction due to interference from other electronics. Imagine an electromagnetic disturbance affecting a medical imaging device, resulting in blurry images. Such distortion can hide crucial details, leading to misinterpretation by radiologists and potentially incorrect diagnoses!
  • Market access:  many countries require EMC compliance for electronic products to be sold within their borders. Failing to comply with these regulations can result in legal penalties, including fines, bans, or recalls of non-compliant products.
  • Safety: uncontrolled electromagnetic emissions can create safety hazards in medical settings, they can cause critical devices such as pacemakers, and defibrillators to malfunction, leading to incorrect pacing of the heart, and failure to deliver life-saving shocks. In aviation systems, they can create incorrect instrument readings, loss of communication with air traffic, and compromise flight safety. In automotive systems, they can disrupt airbag deployment systems or electronic stability systems resulting in accidents and irreversible damages.

Testing Services Illustration

The above image illustrates an example of a basic setup used to measure radiated electromagnetic disturbances emitted by a specific device. The equipment is positioned within a semi-anechoic chamber, which provides an environment devoid of unwanted external signals. An antenna is positioned at a standardized distance to detect the emissions generated by the Device Under Test (DUT). These emissions are then transmitted through a cable to an interference receiver, which charts the measured emissions, comparing it to the levels specified by the client.
