Protecting Your Electronics from Electromagnetic Interference

Foam provides EMI shielding for mission critical components on aircraft such as navigational and GPS systems.  The tortuous nature of the material prevents the EMI interference from bombarding the equipment.

Electromagnetic interference (EMI) poses a significant challenge in modern electronic systems, affecting the performance of devices from telecommunications to aerospace. 

Duocel® provides a highly effective, lightweight material for EMI shielding.  The porosity of metal foam allows it to attenuate electromagnetic waves effectively by absorbing and scattering them, reducing the risk of interference.

Advantages of Metal Foam in EMI Shielding

  1. Lightweight Structure: Compared to solid metal shields, metal foam offers lower weight while maintaining high shielding effectiveness, making it ideal for aerospace and automotive applications.

  2. High Surface Area: The porous nature of metal foam increases the surface area available for absorption and reflection of electromagnetic waves, enhancing shielding performance.

  3. Thermal and Mechanical Properties: Apart from EMI shielding, metal foam exhibits superior thermal conductivity and mechanical strength, contributing to better heat dissipation and durability in electronic devices.

  4. Environmental Benefits: Metal foam is recyclable, making it an eco-friendly alternative to traditional solid metal shielding solutions.

Applications of Metal Foam in EMI Shielding

  • Telecommunications: Metal foam is used in casings, base stations, and networking equipment to minimize signal interference.

  • Medical Devices: Sensitive medical equipment, such as MRI machines and diagnostic tools, benefit from metal foam shielding to prevent electromagnetic disruption.

  • Aerospace and Defense: Aircraft and military communication systems rely on lightweight and durable shielding materials, making metal foam an ideal choice.

Metal foam represents a breakthrough in EMI shielding technology, offering a unique combination of lightweight properties, high effectiveness, and efficiency. Its adaptability across various industries highlights its potential to replace traditional shielding methods. Metal foam plays a crucial role in advancing EMI shielding solutions, ensuring the reliability and functionality of electronic devices in an increasingly interconnected world.
