Hello, David.

I had made inquiry about such layers because I believed, erroneously as it turned out, that I was having signal-to-signal isolation difficulties as a consequence of magnetic coupling between signal carrying traces on opposite sides of a copper ground plane.

Although I no longer believe that I need non-copper layers, it's good to know that they do indeed exist.

Thank you.
