Abstract

There is disclosed a high frequency attenuation cable. The cable consists of a core which includes at least one conductor, a high frequency absorption medium and dielec­ tric material. The high frequency absorption medium com­ prises soft magnetic elements having an aspect ratio of about 3 or greater. The high frequency absorption medium may also include particulate elements loaded in a polymeric material. There is also disclosed a high frequency attenua­ tion harness which includes a plurality of high frequency attenuation cables.
