There is considerable military interest in the utilization of rare earth-cobalt permanent magnets to facilitate the currently contemplated extension of device operating frequencies into the millimeter-wave region and to enhance the efficiency of devices operating at presently employed frequencies. Specific examples of proposed devices traveling-wave tubes TWTs, crossed-field amplifiers, etc. are discussed, and expected magnet property requirements which would make them viable are reviewed. Future military millimeter-wavemicrowave needs are presented and discussed in terms of magnet materials technology, and circuit design, and the requirement for improved quality control. Author
