ABS-WK is an open-cell lossy honeycomb material used to dissipate in a controlled way electromagnetic energy in to the capillary shaped material. Two different octagonal cell sizes are produced, 3 and 6mm diameter, typical thickness of the sheets are 13 and 25mm. The material can be used in broad band free space application but also finds application in electromagnetic transmission lines both rectangular waveguides and also coaxial systems. Within the transmission lines the material works as attenuating filter or as load terminations, typically used in spiral antenna elements. Due to it’s open cell structure it permits circulation of air as such the material is also used within high power applications. ABS-WK has a very low weight which allows the absorber material to be used in aerospace applications where weight is a key factor.

ABS-FGA is very specific material as the base material is a lightweight ceramic foam material. The ceramic foam material has conical holes which are treated with an artificial dielectric loaded coating, which gives the material excellent lossy properties. Due its shape and lossy properties the material has a very good impedance matching over a broad frequency which is typically from 2 to 18 GHz.

The ceramic base material allows a high temperature usage so this absorber finds it way in high power application with typical power handling capability up to 2,5 W/cm². Power handling capability is always related to the ventilation the material is exposed to, some of the cones can be foreseen of a hole for fixing and air transfer. The material is inorganic and does not burn, the absorber blocks can be stacked on top of each other to create an absorbing wall.

ABS-TLF is a material to absorb unwanted reflecting signals at the RFID UHF frequency range. With its specific thickness the absorber material is designed for optimum absorption at the center frequency 868 MHz, ABS-TLF is used on RFID item reader tunnels and loading stations, the absorber material is able to separate adjacent reading systems which might interfere which each other.

The dimensions of the absorber blocks can be customized to match the size of the application.
