Ferrite tiles, flexible absorber sheets and pyramidal absorbers are made for absorbing electromagnetic radiation. Ferrite tiles and pyramidal absorbers for example are used to create anechoic chambers or boxes. Flexible absorber sheets are generally used to absorb radiation at the radiation source in electronics enclosures. Microwave absorber foam can be used at higher frequencies than traditional shielding and can also be used with other EMI/RFI shields to extend the frequency range.

Ferrite absorbers

Very high frequency ferrite absorber tiles are the standard solution in the industry. They have an excellent overall performance versus cost.

Ultra high frequency ferrite absorber tiles provide excellent electromagnetic absorption in the UHF band. For mobile phone inspection boxes and EMC chambers.

Double-layer ferrite absorber tiles are made according to a special design for small EMC anechoic chambers and show excellent electromagnetic absorbtion performance between 30 MHz and 2 GHz.

Wide-band hybrid EM absorbers are suitable to build small anechoic chambers. In these chambers, absorption can be increased from 1 GHz to 18 GHz by these piramid absorbers.

Flexible absorber sheets

EMI flexible absorber sheets are developed for electromagnetic wave absorption and noise suppression. EMC problems are solved by attaching these sheets on noise sources.

These absorbers operate approximately between 1 GHz and 18 GHz and have a return loss of max. -6 dB

The material can be used at the same time as a electromagnetic waves absorber and as a thermal conduction material.

It is suitable for the medium and low bands (FR1) below 6 GHz (Sub6G) in 5G NR (New Radio) technology because of the high frequency absorbing characteristics.

High-performance EMI flexible absorber sheets are developed for EM wave absorption and noise suppression. EMC problems can be solved by attaching them on noise sources.

These absorbers operate approximately between 1 GHz and 6 GHz and have a return loss of max. -11 dB

These sheets are mainly used to reflect metal components inside a radar cabin or for other applications that require a thin sheet and no broadband absorption.

These absorbers operate approximately between 2 GHz and 40 GHz and have a return loss of max. -18 dB

This RoHS-compliant, coated open-cell foam is used as a microwave-absorbing material, especially for applications with frequencies ranging between 1 and 17 GHz.

These absorbers operate approximately between 1 GHz and 17 GHz and have a return loss of max. -16 dB

Pyramidal absorbers / PU-foam based absorbers

These absorbers are the most popular solution for EMC chambers of 3m, 5m and 10m.

These absorbers are the most popular solution for EMC chambers of 3m, 5m and 10m.

These absorbers deliver the same performance in low frequencies as PU-foam based pyramid absorbers 3640 but their performance in high frequencies might be slightly lower

The main advantage is to reduce the back scattering of pyramid absorbers and to obtain higher quietness of quiet zone

The Nonflammable high power handling absorber is a non-woven fabric-based, hollow broadband microwave absorber impregnated with fire-retardant, which offers microwave absorption

These absorbers are mainly applied in high-power shielded cabinets and ventilation vents of anechoic chambers
