Motorola's MECL System Design Handbook has a few TDR plots which show the
effects of cutting ground under traces. See figures 7-11 on page 137 and
7-13 on page 139.

<excerpt><fontfamily><param>Arial</param><smaller>Hi all,
I am trying to find the effects of the gaps on the ground plane for the
high-speed circuits.
Even though I have a couple of references about the via, which has the
ground gap problem, I need more specific data about the ground gap
problem regarding the gap size, gap location.....
Either measured data or simulated data will be fine ( papaers or refernce
book...)
Looking forward to your answers.
