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

VHF ferrite absorber tiles
3600

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

UHF ferrite absorber tiles 3610

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 3620

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

Hybrid pyramidal EM absorber 3630

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

Flexible absorber sheets

EMI Flexible absorber sheets 5780

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

High-performance EMI absorber sheets 5790

High performance EMI/RFI absorber sheets

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

Rubber, flat narrowband absorber 5795

Rubber flat narrowband absorber

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

Microwave-absorber foam 3500

Microwave absorber foam for EMI/RFI Shielding

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

PU-foam based, pyramid absorbers 3640

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

PU-foam based, flat absorbers 3650

PU Foam based flat absorbers

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

Hybrid absorbers for EMC anechoic chamber 3660

PU Foam based flat absorbers

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

PU-foam based wedge absorbers 3670

PU Foam based wedge absorbers

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

Nonflammable high power handing absorbers 3680

Nonflammable high power handing absorbers

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

High power handing microporous pyramid absorbers 3690

Nonflammable high power handing absorbers

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

High-power SiC pyramid absorbers 3695

Nonflammable high power handing absorbers

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

Rubber pyramid absorber 5796

Rubber pyramid absorbers

Absorbs electromagnetic radiation between 1 and 40 GHz, between 6 dB and 25dB depending on the particular frequency range.
