Of course when they were using .1" wide traces back in the 70's
they didn't have sub-100 ps edges to worry about. I can't see
the relevance to the sharp corner effect to signal integrity
concerns for any commercial applications for a couple of decades
after that work was introduced. Maybe some of us will need to
be concerned about corner effects now or in the near future.
Also, my perceptions is that RF designers have to deal with the
corner effects for their type of work. BTW, I think the handbook
was and still is to some degree one of the best SI resources
available.
