I guess I don't understand any of the above. Coherency just means the
signals are of the identical frequency. Coherency doesn't specify phase.
The phase of a reflected wave can be anything depending on feedline
length and load.

Hi Cecil,

This shows the lack of your "optics." A laser which amplifies by
virtue of coherency, consists of a phase locked aggregation of what
would have been incoherent illuminations. It would be an LED
otherwise.

As I have said for quite a while now, it is a simple matter of
interference math. Such math shows everything of coherency or
differences. A coherent signal, is by definition of the same
frequency of another who matches that coherency.

To put it ironically, the challenge I offer is deliberately incoherent
to give that math a deliberate solution that is other than the result
of simple addition or subtraction.
