A lossy dielectric device dissipates, absorbs, and/or dampens electric fields. The lossy dielectric device may be used with any transmission path, such as a transmission line or resistor in a probe head. The lossy dielectric device preferably includes a lossy dielectric material contained within a container....http://www.google.fr/patents/US7525328?utm_source=gb-gplus-shareBrevet US7525328 - Cap at resistors of electrical test probe
