ElectroMagnetic Simulation (EMC) - A new service available at LabShare!

We at LabShare strive to present the widest possible range of testing services on our platform. Thus, we are glad to announce that EMC simulation is now offered by our supplier as part of our one-stop shop concept. But what exactly is EMC testing, and why is it particularly important?

In today’s world, the function of electronic systems is essential - not only for the success of a particular mission, but also from a security point of view. Interference in such systems can lead to global-scale disruptions, from 5G to autonomous vehicles.

Due to the ever-increasing requirements and the growing number of electronics, the risk of interference is higher than ever before. And when it happens, it can easily compromise performance or cause unintended consequences. However, by testing interference, these issues can be dealt with in advance.

ElectroMagnetic Compatibility, or EMC means that a device is compatible with its electromagnetic (EM) environment, thus, it does not emit levels of EM energy that cause electromagnetic interference (EMI) in other devices.

The goal of EMC, or ElectroMagnetic Compatibility testing therefore is to measure the amount of electromagnetic interference (radiated and conducted emissions) from your device, in order to ensure that it can function in the vicinity of other electromagnetic devices or phenomena.

    EMC’s two main categories are:

  • Immunity testing that measures how a device will react to electromagnetic noise or other disturbances and helps to determine whether it will operate as intended.

  • Emissions testing that measures the amount of electromagnetic noise generated by a device during operation. This test can ensure that the emission is below the required limits, thus, it is not likely to interfere with other devices in its operating environment.

EMC testing is particularly important for medical devices, which must be able to cooperate efficiently without interference. In the EU, all medical devices require CE marking, for which both immunity and emission tests are necessary. Military and aerospace equipment also must undergo EMC testing regarding emissions and electromagnetic susceptibility. In addition, EMC testing is compulsory for some consumer goods, such as microwaves, mobile phones and laptops.

Tests make it possible to observe how various phenomena might affect a product, such as voltage drops due to power interruption, surges due to a lighting strike, or the magnetic field radiation from electrical wires.

How is EMC simulation more effective than traditional tests?

A risk of EMC testing is that it is normally performed towards the end of the development, and often it is only remembered at the very end of a project. When an unexpected problem is uncovered, it might necessitate the modification or the complete change of design, causing a huge a delay in the product release.

Simulation, on the other hand, can be applied throughout the product development cycle, allowing for the comparison of different designs. Simulations can be useful for predicting issues at an early stage. They can also provide insight into already existing EMC issues, for instance, through visualization. In other words, simulation speeds up design and helps improve the end product quality.

Our partner, Abaton Systems Ltd. provides electromagnetic simulation support at their Radio Frequency Test Laboratory, both as a standalone or a supplementary service.

“In order to help our customers achieve EMC compliance, we are prepared to support the electromagnetic design of any product by simulation methods. We provide various types of simulation services for any sort of EMC related issues at any stage of a product development cycle” - says Péter Prukner, Quality management leader at the Radio Frequency Testing Laboratory of Széchenyi István University.

Two main fields of Abaton’s services is electromagnetic compatibility support and high frequency design, by which they provide simulation solutions even for complex RF demands. Among others, this entails the design, tuning and optimization or just analysis of any type of antennas regardless of the application frequency.

They are similarly well-versed in the design of test fixtures for various purposes, be it a simple impedance tester or a precision board for mode conversion loss testing. In addition, they offer the design and study of passive RF and uWave devices. Abaton’s simulation portfolio includes (but isn’t limited to) preliminary circuit-level study, layout investigation, co-simulation of 3D structure with circuity and virtual EMC testing.

All of these activities are supported by market leading, full wave simulation tools and proper hardware environment - so if you are looking for a reliable laboratory for EMC simulation, Abaton Systems and LabShare have got you covered.
