Cavity resonance
In the context of electromagnetic compatibility (EMC), it may be necessary to isolate components emitting unwanted electromagnetic radiations from the others, using a metal housing as Faraday cage. However, reflexions on the inner walls of the housing create stationary waves that can interfer with the emitting component itself. HYMMAG'IN's absorbing materials can address this issue.
Interferences due to stationary waves can be reduced thanks to two methods:
- reducing the amplitude of the vibration antinodes and reduce the intensity of interferences
- moving the vibration antinodes to locations without electronic components
These elements being highly related to the components and the geometry of the housing, an absorbing material expected performances are assessed by its attenuation coefficient, expressed in dB/cm.
