Abstract :
The ring-and-bar slow-wave circuit is analysed using an approximate field-theory approach. The analysis takes into account the effect of surrounding shields, finite bar thickness and dielectric supports. For those cases where a comparison with an earlier and more rigorous theory is possible (thin bars, no supports), the agreement obtained is excellent. Extensive computations of both dispersion characteristics and impedances have been carried out, and are presented in a series of graphs.
