Microwave absorbers

Our wide range of electromagnetic absorbers for microwave testing

We have developed a whole range of absorbers tailored to the tests to be carried out:

  • Antenna measurements (radiation pattern, VSWR, PIM)
  • RF systems verification (satellites, WiFi, mobile phones, 5G …)
  • Radar characterization or Radar Cross Section (RCS)

All the following models are used in new installations or for chamber refurbishment and upgrades. Depending on your needs, our expertise allows us to offer you the right absorbers for a specific chamber design, instrumentation and / or installation

SEA-PM – Broadband pyramidal absorbers

SEA-PM – Broadband pyramidal absorbers

Pyramidal absorbers used for the lining of anechoic chambers for antenna measurements (compact ranges, Radar Cross Section (RCS), Over-The-Air (OTA), IoT, 5G …)

Our assets:

Range of sizes and performances depending on the need and the space available.

SEA-MP – Mid-power absorbers

Absorbers designed to handle high power up to 3.2 kW/m². They equip the specific areas of compact bases and antenna measurement chambers dedicated to telecommunications/wireless, satellite, defence,..

Our assets:

SEA-HP – High-power absorbers

These honeycomb absorbers can handle high powers up to 15 kW/m². The SEA-HP equip the specific areas of compact bases and antenna measurements chambers dedicated to telecommunications/wireless, satellite, defence,…

Our assets:

Range of sizes and performances depending on the need and the space available.

SEA-WM – Wedge shape absorbers

These wedge-shape absorbers are integrated into compact bases and anechoic chambers. SEA-WM are designed to ensure high performance in chambers with incidence angles above 50°. The dihedral shape of the SEA-WM, guiding the reflected wave, can be integrated into anechoic chambers for the measurement of antenna patterns or Radar Cross Section (RCS).

Our assets:

Range of sizes and performances depending on the need and the space available.

SEA-WW – Walkway absorbers

Flat and rigid absorbers, their technology (PU foams wrapped into vinyl cover) allows access to the equipment in a full anechoic chamber.

Our assets:

Range of sizes and performances depending on the need and the space available.

SEA-MLM – Multi-layer absorbers

SEA-MLM is a premium series of broadband high-end multilayer absorbers. Two references are proposed: SEA-3LM (3 layers) and SEA-5LM (5 layers). They are used to cover all metallic surfaces, masts and antenna bases. They also contribute to the reduction of coupling effects between antennas. Despite their low apparent thickness, SEA-MLM offer high levels of absorption.

Our assets:

Range of sizes and performances depending on the need and the space available.

SEA-F – Flat absorbers

Flat absorbers for covering corners in fully anechoic and semi-anechoic chambers.

Our assets:

Range of sizes and performances depending on the need and the space available.

SEA-WP – Weatherproof absorbers

SEA-WP are pyramidal absorbers sealed in a coating that guarantees the weatherproofness of the material. They are therefore used outdoors to cover metal areas or to reduce the Radar Cross Section (RCS),…

Our assets:

Range of sizes and performances depending on the need and the space available.

SEA-CM – Convoluted absorbers

SEA-CM are absorbers with convoluted shape typically used to cover masts or antenna positioners in anechoic chambers. Low height absorbers, they allow to work on high frequencies.

Our assets:

Range of sizes and performances depending on the need and the space available.
