Ah right, so uneven on a microscopic scale, flat on the macro one. Makes sense, thanks!

Correct me if I'm wrong, I have next to no knowledge on stealth fighters and detection technology.

Isn't an uneven surface desirable in a fighter jet, though? From a radar-evasion standpoint. I remember reading something to that effect in a book a long time ago.

Ah, shame.

Any sources or further reading i could do there? Sounds interesting, I just haven't heard anything about this so far.
