14KHz to 18GHz meet 100dB RF shield room
We utilize other materials and techniques when requested for special purposes such as architectural, copper, and textile shielding. The fully integrated system consists of several shielding components such as panels, doors, honeycombs, windows, access panels, electrical filters and a large range of shielding penetration elements for all kinds of media interface.
Many of these components require a ductile, stable, and long lasting RF-tight joint to the shielding itself. For this purpose we have developed a RF mesh capable of performing from several kHz to 40 GHz. Individual components were developed with the focus of achieving superb electromagnetic shielding performance with the understanding that the limit of effectiveness would be set by the weakest component.
When a shielded room is necessary?
· If your lab is near a broad spectrum emitter (i.e equipment that transmits multiple frequencies under 400Hz), radio tower, mobile phone transmitter or other large field generators, then you should consider a shielded room.
· If your research is in the gamma band and you do not want to use a 60/50Hz notch filter to remove mains power noise, you might consider a shielded room. We recommend taking the steps above to first minimize the mains power noise. If that is not sufficient for your needs, then a shielded room may help.
