Title :
Interpretation of slimguide operation in terms of propagating (nonevanescent) waves

Abstract :
It is shown that the capacitive loading of the tuning stubs enables the medium to be interpreted as a periodic-loaded waveguide with propagating characteristics in the passband. Broadbanding requires close stub spacing; a preferred operating region is suggested.
