Re: [Phys-L] causality

Somewhere I read that the K-K transform implies causality — the argument was (even more so now) beyond my intelligence.


bc used it as a check of his ellipsometer data (N = n-ik) of metals.


p.s. Here’s this, which, from JD’s analysis, skimming appears fallacious.

the other way around.

That's not what the equations say.
That's not how the fundamental physics works.

Like a net force makes an object accelerate
