1. An arrangement to eliminate multipacting in radio frequency (RF) devices disposed in a vacuum-like environment comprising:

  • a RF device disposed in said environment, said device having two RF electrodes capable of supporting multipacting in a RF high voltage region therebetween; and

    a dielectric material having a given dielectric constant and a given dielectric strength disposed between said two electrodes in at least said region to eliminate multipacting, said dielectric material completely filling said region;

    said environment is space; and

    said RF device includinga microwave filter having a cavity with a cavity wall providing one of said two electrodes and a plurality of resonators providing the other of said two electrodes; and

    said dielectric material fills said cavity.
