Should have been more specific

I believe most designers are blind to the effects of EMI induction. Oh yeah, we know the theoretical aspects, but addressing the inductive qualities are often ignored. For example, take the use of circuit boards and the effect of adjacent traces. Why is it that removing a metal chassis cover almost invariably opens up the upper frequencies?

These are not difficult issues to address but very few designers actually take the time to rectify them.

About 25 years ago, when being trained as a CADCAM systems manager, I came across a program to calculate the effects of EMI induction in circuit boards. Back then it was a $100k program, but I never saw anything further.
