Abstract

Comb and meander line structures, which have been used in travelling wave masers, have been modified for use with solenoids. A theory for the determination of the dispersion characteristics of these structures has been outlined. Various methods for modifying the characteristics of a slow wave structure to suit travelling wave maser applications are also discussed. Propagation along open comb and meander line structures was studied in the L band. A method was developed for the direct measurement of group velocity. Experimental results indicated that both the modified comb and meander line structures could be used in travelling wave maser circuits in conjunction with solenoids.
