OUR FREE SPACE DESIGNS
OUR 3D NARROW-BAND ABSORBERS
Discover our honeycombs for narrow-band absorption! Our honeycombs have a significant absorption performance at 10GHz with its specific dimensions: 3mm thickness, 7.5mm cell radius, 3mm wall thickness.
Our honeycombs are not limited to these capabilities.
By modifying the thickness distribution of the cell wall, we adapt the impedance matching to facilitate the absorption of the wave in the material.
We can configure the dimensions of the honeycomb to shift the absorption peak on higher or lower frequencies according to your EMC requirements. In addition, we are also developing interlocking double honeycomb designs to obtain two resonance frequencies.
OUR 3D BROAD-BAND ABSORBERS
Do you need to absorb at a wide frequency range? Extend your frequency range efficiency with this multilayer square structure. The different thicknesses of the layers will enable you to absorb waves over a wide range of frequencies in the GHz.
Examples of uses in free space:
- Avoid interferences on antenna radar. Consider a metal boat mast in close proximity to the radar signal. This results in wave reflection perceived by the radar. By applying our free space absorbers onto the mast, you avoid unwanted reflections and improve the effectiveness of your detection.
- Reduce Radar Cross Section (RCS). Apply our solutions to your devices to prevent waves from being reflected back and benefit from radar discretion.
- Absorb a target frequency in your specific anechoic chambers. In a small-volume anechoic chamber dedicated to 5G (3.5 - 3.8 GHz) for example, use our honeycomb absorbers to cover the walls and eliminate wave reflection.
OUR NEAR-FIELD AND RESONANT CAVITY DESIGNS
OUR 3D MAGNETIC CASE
Protect your electronic boards with our 3D magnetic case! Lighter than a traditional metal case, our solution prevents the transmission and reflection of waves by its ability to absorb them.
Examples of uses in near-field and resonant cavity:
- Suppress the radiated emission from your PCB components. Reduce the noise emitted by a microcontroller for example by applying an absorber directly on it.
- Eliminate resonant cavity formed by metal casing. Add an absorber inside the metallic casing or replace it with a 3D-printed composite casing to protect your components and prevent waves from being reflected on the metallic surface.
With specific designs, you can increase your EMC solutions’ performances while reducing their weight and so the weight of your on-board system. This contributes to decrease your energy consumption and to meet the challenges of decarbonisation.
