The reference sources report some attempts to develop CM capable of generating at a wave length below 8 mm, however the experimental specimens failed to provide any satisfactory parameters. The related publications lack any unified concept as for CM design. The available recommendations concern the centimeter wave band and are not free of errors. The problems associated with expansion of CM into the short-wave part of the millimeter (mm) wave band are also well known, still there are no suggestions as how to overcome them. In this paper the author suggests a technique of developing a millimeter wave band CM, comprising the most recent achievements in this area (e.g. the possibility to use the mode of interaction between the electron beam and a higher spatial harmonics of π-oscillation mode). Special attention in this paper is given to finding possible solutions of some problems associated with the CM expansion into the short-wave part of mm wave band, like a higher density of frequency tuning, increased heat load on the segments, reduced stiffness of the cylindrical part of the anode slowing system. The suggested method provides a basis for developing a CM suitable for short-wave part of mm wave band. This study proves the feasibility of designing a functionally operative 4-mm CM. %8 2013-08-26
