To minimize interference and reflections within and between electronic systems, broadband absorber materials play a crucial role. A leading manufacturer in this field is ABS Technics, supplying a wide range of advanced absorption materials that meet the strictest requirements of modern applications.

The ABS-SLF series is a lightweight material composed of carbon-filled foam, designed to absorb a broad frequency range of electromagnetic waves. The flat plate of the standard 6210x610mm has a multi-layer structure consisting of individually tuned absorbing layers, each with its specific dielectric gradient, to achieve the best possible impedance matching with air. The absorbing plates are impregnated with a binder and enhanced with fire-retardant additives.

The ABS-SLF series is available in 6 different thicknesses ranging from 6 to 114mm, with each type related to its operating frequency, from >0.8 to >20GHz. The typical reflection level at microwave frequencies is better than -17dB relative to a metal background.

ABS-SLF is a typical broadband absorber used in free space and cavity applications indoors or semi-outdoors. For specific applications where the absorber is used in a harsh environment, the absorbing material can be provided with protection such as vinyl, PVC tissue, or a coating.

Typical broadband applications include reducing the reflectivity of metal structures and masts, minimizing crosstalk between antenna systems, modifying radar cross-section (RCS), or enhancing stealth applications.

ABS Technics has built an excellent reputation as a manufacturer of top-quality broadband absorber material. Their absorption materials are designed to meet the stringent demands of modern electronic applications and offer unique advantages.
