Currents induced on coaxial cable shields are common in MRI due to the E fields present in the bore during the RF pulses. These cable modes can increase SAR. Cable modes can result from coupling between cable and any coil. They affect the tuning and isolation. The standard method to eliminate cable modes is a balun. We present a different method to damp the cable modes using conductive plastics. This method is broadband, and inexpensive.
