Hello Everyone,
Just uploaded another demo of possible unusual crosstalk between
differential striplines and viaholes: #2019_10 at
http://www.simberian.com/ScreenCasts.php ;
or at youtube at
https://youtu.be/zKXTUVP8Wnc ;
Again, power flow density is used to illustrate the coupling. In general,
striplines are open waveguides and anything that gets into the area with the
substantial power flow becomes coupled, it may cause problems and such
effects should be either simulated or boards re-designed to avoid it.
As usual, I will appreciate any feedback or suggestions.
Best regards,
Yuriy
