Abstract
A coaxial cable comprises at least one internal conductor and a surrounding cable shield. A plurality of sheath wave barriers are arranged along the cable shield, each having two ends that are coupled to the cable shield at coupling points of the cable shield that are spaced from one another. The coaxial cable is exposed to a radio-frequency excitation field with an excitation frequency, due to which sheath waves can be excited on the cable shield. The excitation field is shielded from the at least one internal conductor via the cable shield. The sheath waves can be damped via the sheath wave barriers. A detection circuit is associated with at least one of the sheath wave barriers, from which detection circuit a measurement signal characteristic of a load of the respective sheath wave barrier due to the excitation field can be generated. The measurement signal can be tapped and evaluated.
