Screens for RF magnetic flux |
摘要 |
Microstructured materials which can be tuned to a particular range of r.f. frequencies to display particular magnetic permeabilities have been proposed. A typical material is made of an array of capacitive elements e.g. spirals or rolls of conducting material on a non-conducting substrate. These materials can be used as screening material which is effective for the particular band of frequencies to which it is tuned. In one example, the rolls 2 to 5 are orientated normal to the face of the screen 1, which reflects or absorbs the magnetic vector of electromagnetic radiation impinging normal onto the reflector face.
