HYMAG'In Showcases EMC Applications At Electronica 2024

Hymag'In, a French company, has become a pioneer in manufacturing magnetic iron oxide nanopowders critical to future technologies such as telecommunications, electronics, and aeronautics. The company produces these advanced materials locally in Europe. Their materials are designed for applications in electric vehicles, 5G networks, and embedded systems, where stringent specifications for magnetic properties are essential for optimal functionality.

At Electronica 2024, Hymag'In demonstrated concrete EMC applications using the latest electromagnetic absorbers.

1. Transceiver (Receiver-Emitter)

In the realm of the near field, managing electromagnetic emissions is crucial. The near field refers to the immediate area around an antenna where electromagnetic fields are highly concentrated.

Hymag'In absorbers are strategically placed directly on the metallic casing, effectively preventing unwanted wave transmission by concentrating electromagnetic energy within the material and converting it into thermal energy. Thanks to their 3D-printed solutions, these absorbers seamlessly adapt to the compact dimensions of transceivers, ensuring perfect integration even in the tiniest systems.

2. AC/DC Converter

Hymag'In absorbers are used in AC/DC converters to eliminate internal standing waves caused by reflections within metallic housings.

Resonant cavities, where electromagnetic waves bounce and create interference, can disrupt component functionality. Hymag'In absorbers enhance performance by reducing vibration amplitudes and strategically relocating wave peaks. Additionally, placing absorbers on transformers demonstrates the adaptability of 3D-printed products to various shapes and spaces, proving their versatility beyond transceivers.

3. Anechoic Chamber

Experience top-tier electromagnetic compatibility with Hymag'In's anechoic chamber setup.

The chamber walls incorporate a variety of Hymag'In absorbers, including honeycomb, double honeycomb, multi-scale square, and peak designs. These geometries showcase Hymag'In's potential to produce tailored solutions through 3D printing.
