EMI/RFI Solutions: Protection and Shielding Against Electromagnetic Interference

Technological Shielding & Filtering to Ensure Full Electromagnetic Compatibility (EMC)

In a world where electronic systems are becoming denser and more sensitive, managing Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) is a mandatory condition for proper product functionality and compliance with strict international standards. At Wave Components, we are proud to represent global market leaders Laird Performance Materials, Okaya, and Andertech, providing solutions that cover all shielding stages—from the component level to the full enclosure.

Our Specializations in Shielding and Protection:

Fabric-over-Foam (FoF) Gaskets

Laird’s FoF gaskets consist of a flexible foam core covered with a conductive fabric.

• Application: Sealing gaps in doors, covers, and electronic enclosures.
• Advantage: Extremely low compression set and low closure force, protecting the mechanical structure while ensuring excellent electrical continuity.

Conductive Elastomers

Solutions by Laird combine silicone rubber with conductive metal particles (such as Silver, Aluminum, or Nickel).

• Application: Military and Aerospace applications requiring resistance to harsh environmental conditions.
• Advantage: Provides environmental sealing (water/dust) combined with exceptionally high EMI shielding, compliant with MIL-STD-461.

RF Absorbers

Magnetic or dielectric materials, such as Laird’s Eccosorb™ family, convert electromagnetic energy into heat and are designed for high frequencies.

• Application: Preventing internal cavity resonances, improving antenna performance, and reducing RF noise from specific components.
• Advantage: A “silent” solution for radiation issues without requiring changes to the enclosure’s mechanical structure.

EMI/Noise Filters

The product line of the Japanese company Okaya, including power line filters (AC/DC) and noise suppression capacitors.

• Application: Protecting power inlets in medical devices, industrial equipment, and communication systems.
• Advantage: Cleans Conducted Emissions and prevents voltage surges.

EMI Windows and Honeycomb Vents

Solutions that allow “openings” in the enclosure without compromising shielding integrity.

• EMI Windows: Glass or Polycarbonate integrated with a conductive Mesh, allowing a clear view inside a shielded enclosure.
• Honeycomb Vents: Ventilation panels that allow maximum airflow for system cooling while blocking RF waves (waveguide beyond cutoff principle).
