Image Number 2 for United States Patent #6686543.
A radio frequency suppressing cable has at least one conductor and a resistive layer surrounding the at least one conductor and insulated from the at least one conductor. The bulk resistance of material included in the resistive layer is greater than that of the material of the at least one conductor. In addition, the thickness of the resistive layer is greater than the skin depth .delta. for the radio frequency, where ##EQU1## where .sigma. is the conductivity of the material, f is the frequency, .mu..sub.r is the magnetic permeability relative to that of free space, and .mu..sub.o is the magnetic permeability of free space.
