Hi,

Does anyone have these design papers:

Stracca, G. B.; Panzeri, A. "Design optimization of slab-line resonators for compact microwave bandpass comb-filters"

G.B. Stracca, G. Macchiarella and M. Politi, ?Numerical Analysis of Various Configurations of Slab Lines,? MTT-34, No. 3, March 1986, p.359-363.

Thanks.
