HONEYCOMB - MICROWAVE ABSORBERS
The honeycomb structure is optimized for the absorption of electromagnetic waves on a targeted frequency. This honeycomb design maximizes absorption efficiency while maintaining a light weight and robust mechanical structure. By adjusting the dimensions (cell diameter, wall thickness, angle of inclination), absorption can be calibrated to a specific frequency in the GHz range.
Shape: Honeycomb structure.
Dimensions: Adjustable dimensions to target other frequencies.
Use frequencies: Adjustable on request and according to the constraints of your systems.
Below the results of a 3D honeycomb pattern designed to absorb in the dozen of GHz: significant reflection losses of -16 dB around 12 GHz and a weight three times lighter than a 3D sheet of the same thickness.
-16 dB around 12 GHz
This architecture shows resonance when the cell dimensions correspond to a quarter of the targeted wavelength. This wave will be reflected many times in the cells, generating a progressive absorption of the wave.
More elaborate architectures can be developed on request, in particular to enable multiple resonances.
New architecture breaks down into multi-scale cells. With this shaping, several resonances will appear to allow absorption peaks at different frequencies.
Why choose FILAMAG-F honeycomb structure?
- Lightweight: performance/weight ratio
- Flexible material
- Customized, adaptable
Example of use: This honeycomb is used by device manufacturers and/or users whose aim is to reduce the reflection of electromagnetic waves on the surface of these systems. This is particularly the case for equipment that needs to be made undetectable by reducing its radar cross section (RCS).
So where can this design be applied?
What about HYMAGIN?
HYMAG'IN produces and sells several ranges of innovative ferrite-based magnetic materials.
The products are ultra-fine powders and semi-finished products for additive manufacturing, such as magnetic filaments for 3D-printing, used to solve electromagnetic compatibility (EMC) problems, mainly as microwave absorbers.
