High performance medium frequency non-woven absorbing material
In general, non-woven absorbing materials can be used in EMC measurement darkroom. If the absorption performance reaches - 20dB in the test frequency band, the use requirements can be met. If the darkroom space allows, long wedge absorbing materials (generally 2m or more) can be selected. If the measurement antenna performance is considered, long wedge materials must be used.According to the frequency of measurement and the performance of the static area to be achieved, the materials with different lengths of sharp cones are selected. In terms of layout, the long sharp cones are used for the main reflecting surface and the short sharp cones are used for the secondary reflecting surface.If the darkroom needs a high degree of cleanliness and a high power resistance, a fire-resistant power absorbing material is selected.
