Hello Yuriy,
I'm not surprised that tight coupling is less attracted to weave effect on 3313
glass.
Mechanically spoken, tighter coupling decreases the dielectric differences in
between traces of a differential pair. Look at Figure 5 of your paper and
imagine what the difference of effective dielectric surrounding the traces
would be when the spacing is close to one tracewidth. The difference would be
very small, especially when flat weave or even flattened weave is used.

Betreff: [SI-LIST] fiber weave effect
Hello Everyone,
Some results of our on-going investigation of fiber-weave effect (FWE) were
recently presented at IEEE EMC 2014 symposium (at SIPI section) and the paper
and presentation are now available at http://www.simberian.com/AppNotes.php -
see #2014_04.
One of the interesting outcomes was practically negligible FEW impact on the
tightly coupled traces on spread fiber fabric (voltage coupling coefficient
about 0.2). We have observed it both on strip and micro-strip (one sheet of
dielectric fabric) configurations.
We did not find any published confirmation of this result. Any comments or
thoughts?
Best regards,
Yuriy
