Abstract
A damping element for use with a waveguide that supports a current pulse and results in a torsional or longitudinal strain wave is disclosed. The damping element is to dampen the reflection of the strain wave and includes a sleeve surrounding the waveguide and a mechanism for applying pressure on the sleeve so the sleeve exerts pressure on the waveguide, thereby gradually dampening the strain wave energy along the length of the waveguide surrounded by the damping element sleeve to prevent reflection of the strain wave.
