Abstract :
As an application of the theoretical method described in a companion paper L.P. Dunleavy and P.B. Katehi (ibid., vol.36, no.12, p.1758-66, 1988), numerical and measured results for open-end and series gap discontinuities and a coupled line filter are presented. Comparisons are also made to predictions obtained with commercially available CAD packages. The results verify the accuracy of the theoretical method and demonstrate the effects of shielding on discontinuity behavior. The experimental techniques used, which involve the through-short-delay de-embedding approach, are explained.<>
