HYFRAL APM is a range of high performance broadband electromagnetic absorbers.
Each absorber consists of a single block of high tech polyurethane foam that is pyramidal-shaped and impregnated with a sophisticated carbon-based aqueous solution.
HYFRAL APM are suitable for broadband applications and are used to line semi-anechoic and fully anechoic chambers for antenna measurements Radar Cross Section compact ranges telecom EMC military applications.

HYFRAL HY is a range of high performance electromagnetic absorbers well suitable to EMC applications.
The combination of SIEPEL FE30Z ferrite tiles performances at lower frequencies and pyramidal matched
absorbers in the upper frequency range results in broadband reflectivity performances from 30 MHz to 18GHz
and beyond enabling the use to HYFRAL HY absorbers in EMC anechoic chambers for EMI and EMS testing according to both commercial and military standards.

Ferrites are resonant absorbers made of ceramic material with metallic oxides (Ni/Zn) available in multiple thicknesses from 4 to 7 mm. Optimal performances are usually obtained with 6.7 mm tiles: down to -35 dB on the central frequency (180 MHz).
Their good performances on the frequency range [30 MHz 1 GHz] (see table below) make them perfectly suitable for most EMC applications in which the use of ferrite tiles makes it possible to optimize the size of the installations and design compact chambers.

With similar performances level to APM the wedged shape of ADM abosrbers makes them efficient for incidence angles > 50° for which they drive the waves and significantly reduce reflections. they are mainly used for high performance chambers for microwave measurements (such as near-field antenna patterns or RCS measurements).

With performances similar to APM APX are pyramidal absorbers with truncated top and reduced height designed to provide efficient space saving in anechoic chambers. The reflections on the flat surface have no any significant impact at low frequencies when APX are installed on non-critical areas.

These absorbers are designed to provide access to antennas and EUT in fully anechoic chambers. They can withstand up to 200 kg/m2 loads with standard base dimensions 1220 x 610 mm. Their performances reach -30 dB as they consist in pyramidal absorbers tied together and sealed in a plastic envelope. Their heat dissipation is 0.13 W/cm2 max continuous with vinyl coating M2.
They can withstand up to 290 V/m max CW.

AHP | HIGH POWER ABSORBERS
HYFRAL AHP absorbers are designed to line specific areas subject to hight power densities (from 2W/cm² CW and above) in applications such as Telecom / Wireless Satellite Automotive Military etc... Thanks to their specific open structure they can withstand hight temperatures resulting from generation of high fields strengths.
HYFRAL AHP absorbers are typically used to line "hot spots" in anechoic chambers were energy is highly concentrated.
