Cortex,
I strongly suggest reading each of those citations carefully, as well
as Dr. Eric Bogatin's "Signal Integrity Simplified" and Lee Ritchey's
test reports on 90 degree bends. Eric's book is the best
quantitative report that I have seen, and his model matches measured
test results obtained with state of the art equipment.
Regards,
Steve.
