Electromagnetics Engineer: Successfully Testing and Managing Electromagnetic Fields

Long-established industries, such as automotive, medical, communications, home, and lifestyle, are being disrupted by an explosion of smart and connected devices. All electric/electronic devices create local electromagnetic (EM) fields, and the way these fields perform and interact with nearby devices, people, and the environment is an important aspect regarding their performance and safety.

Every new electrical and electronic device (electric vehicle, mobile phone, antenna, etc.) must comply with electromagnetic regulations that require the passing of expensive and time-consuming physical tests. An example of regulation impacting a new and emerging market is wearable devices used by operators at logistics plants. These devises must comply with BioEM standards, as well as the related IoT systems that they must connect to.

Virtual Testing

Avoiding the expense, in both time and money, of failing these regulatory tests requires that product design teams adopt a virtual testing approach for EM evaluation during the design process to better understand the implications of both design decisions and component selection on a product’s electromagnetic and signal performance.

Electronics designs have to take into account and manage near and far electromagnetic fields.

Development of smart and connected devices is a multi-disciplinary task. Mechanical, electrical, and PCB engineers all need to work together on a single data set to ensure that all teams are aware of the design approaches the other teams are taking. Each team’s decisions impact the other teams and can affect the EM performance of a product. By using the new SIMULIA Electromagnetics Engineer role, teams can quickly and easily assess electromagnetic fields on their design and see the impact of any design changes on the EM performance of a product.

No matter the industry, as soon as you add electronic systems to a product you must consider the possibility that interference between systems can result in poor product performance or failure.

Managing the Unseen

SIMULIA Electromagnetics Engineer was developed by our sister brand SIMULIA and is powered by the industry-proven CST Studio Suite technology. It delivers high performance 3D High Frequency electromagnetic simulation for analyzing and optimizing electromagnetic components and systems via a seamless, intuitive, and modern user interface on the 3DEXPERIENCE® platform.

SIMULIA Electromagnetics Engineer enables designers and engineers to perform low to high frequency (static to optical) electromagnetic simulations, including the optimization of antennas, microwave components, and electro-mechanical devices as well as some optical applications and charged particles dynamics scenarios. Electromagnetics Engineer assists design teams in improving product performance, reducing time-to-market, and minimizing device malfunctions, warranty claims, and recalls.

The design of motors and generators requires electromagnetic simulation for best product performance.

Safety Matters

With the explosion of mobile and wearable technology, the impact of electromagnetic waves on the human body is causing increasing concern. The simulation of human body exposure to electromagnetic fields via the technology of Electromagnetics Engineer is key to producing safe products.

With its broad range of capabilities and unique capacity to identify and mitigate electromagnetic compatibility (EMC) and electromagnetic interference (EMI) risks in electronic devices, Electromagnetics Engineer ensures that a device will pass any certification tests required by regulatory and industry standards the first time.

Controlling the performance of electromagnetic fields is key for mobile device certification.

Calculating the impact of electromagnetic fields on product performance is only half the challenge, an often overlooked but vital step is to make these results available to everyone on the design team. This is where being connected to the 3DEXPERIENCE platform comes into play. With all the product teams using the platform everyone will have easy access to the latest designs, simulation results, as well as advanced design, data management, and manufacturing tools that will allow you to implement new strategies and workflows.  And of course, being connected means you can collaborate with more people more easily—colleagues, customers, partners, and more—through the cloud-based platform.
