I wonder if this pattern is considered similar to fractals? Or would that work even better? I recently learned that we have figured out how to produce fractal light from lasers as well which sounds quite interesting and useful.
Maybe the reason radio waves travel poorly through trees is due to the leaves having a fractal-like structure as well? And since light is also just electromagnetic radiation too, it makes sense that this phenomenon could also be used to absorb light itself, if I'm understanding correctly. I wonder if this is how stealth paint on aircraft works?
I'm way out of my depth here, but I think this comparison to the birds of paradise feathers makes the most sense in terms of me visualising what Nxylon would look like with a thin metallic coating
