humm, They're making the holes mechanically, but how much more expensive would it be to "print" them like an integrated circuit? film streaming

I’ve built and used anechoic rooms at microwave frequencies (300-10000 MHz) that use the same principle. But the cones are much neater, and reflect much less energy (0.01%). It’s harder making them at sub-visible wavelengths.

Cool stuff but how far away is it from being a commercial product that you can buy and install on your roof?
