A 2mm BEAM WAVE GENERATOR, USING A SPIRALLING ELECTRON . A. H. Beck * and C. J. Caldwell-Nichols + ABSTRACT A 2mm wave generator that uses a helical electron beam spiralling around the axis of a nearly square waveguide cavity is described. The beam interacts with the TElln mode in the cavity and the frequency of gyration around the axis is closely equal to half the signal frequency, thus ha



ELECTRONIC F ERRITES TUNING OF HIGH POWER X-BAND MA.GNETRONS WITH .' J. L. BARRI . and Y. PEYRARD + ABSTRACT:Frequency agile magnetrons are important in radar systems employing transmitter frequency agility to provide improvement in glint, fading and clutter. Electronic tuning is preferred for reasons of speed and reliability, and as such, it has high potential for such applications. Electro

INDUSTRIAL MICROWAVE APPLICATIONS * W.A. Geoffrey Voss ABSTRACT: Industrial microwave applications are rapidly increasing. Their potential in certain areas, the food, rubber and textile industries arises from a combination of advantages: efficient energy conversion, automation and product quality control. Many other heating and drying applications are under consideration today; these include

ACTIVE MICROWAVE Hartwig W. Thim ABSTRACT SEMICONDUCTOR DEVICES This paper presents a survey of active microwave semiconductor devices with emphasis on devices made from Gallium Arsenide which is presently the material with the greatest scope and promise. Thanks to the three properties of high mobility low threshold field and the existence of semi-insulating substrate GaAs is now preferably use
