Abstract: A cable (10) comprises a plurality of mutually insulated conductor (12, 14, 16, 18, 20) and a resistive layer (28) surrounding, and being insulated from, the conductors to prevent radio frequency transmission therefrom. The bulk resistance of material comprising the resistive layer is greater than that of the material comprising the conductors. The thickness of the resistive layer may be greater than the skin depth null, the skin depth null being equal to 1 null = 1 null null null null null null null null f null null null null r null null o where null is the conductivity of the material, f is the frequency, nullr is the magnetic permeability relative to that of free space, and nullo is the magnetic permeability of free space. The thickness is typically between 2 and 10 times the skin depth null.
