Broadband High Frequency RF Wave Absorption

Manufactured from high-resilience flexible polyurethane foam impregnated with conductive carbon black, our RF absorbers convert electromagnetic energy into heat through dielectric loss. The geometric pyramidal and wedge structure gradually matches the impedance of free air, eliminating reflection boundaries across high-frequency bands.

Broadband Performance

Fire Retardancy Rated

Cleanroom Safe Coating

Delivers superior attenuation up to 40 GHz, maintaining high reflectivity reduction for demanding microwave and millimeter-wave measurement protocols.

Fully certified under international fire safety standards including NRL 8093 Tests 1, 2, and 3, DIN 4102 B2, and ISO flammability requirements.

Lightweight and easy to trim, with optional protective elastomer coatings that prevent carbon dust shedding in ISO-classified laboratory spaces.

Antenna & OTA Testing

Radar Cross Section (RCS)

Essential lining for Fully Anechoic and Semi-Anechoic chambers conducting compliant radiated emissions and immunity testing.

Provides low-reflection baseline conditions for antenna pattern measurements and Over-The-Air wireless device evaluations.

Suppresses background clutter in defense testing enclosures to resolve subtle target radar reflection profiles accurately.

Microwave Enclosures

Automotive EMC Chambers

Compact absorbers for small test boxes and custom RF shielding units to prevent internal cavity resonance during manufacturing quality control.

Durable absorber configurations tailored for full-vehicle testing halls, validating electric vehicle drive systems and autonomous vehicle sensors.

Data Sheet & Hybrid System Setup

Physical & Electrical Parameters

Hybrid Ferrite Tile Integration

Material: Carbon-impregnated flexible polyurethane foam matrix.

Absorber panels mount directly to metallic chamber walls or ceilings using contact adhesives or heavy-duty industrial Velcro systems.

Available Profiles: Pyramidal, Wedge, and Flat absorbers.

For complete broadband performance down to 30 MHz, foam absorbers are combined with Ferrite Tiles into a Hybrid Absorber System. The underlying ferrite layer manages low-frequency magnetic wave absorption, while the polyurethane pyramids attenuate high-frequency emissions.

Base Dimensions: Standard 600 mm x 600 mm structural panels.

Absorber Heights: 100 mm, 300 mm, 500 mm, up to 1000+ mm.

Operating Frequency: 80 MHz to 40 GHz continuous coverage.

Environmental Bounds: -50°C to +90°C; 0% to 90% RH operating limits.
