Well, there are 3D printers :)
- sbzodnsbd 8y agoDisclaimer: I find this super cool. I love analog solutions to engineering problems. This is about optical wavelength length scales -> feature sizes << 1500nm for infrared 3D printers’ feature sizes work for giga hertz waves (as a guestimate) assuming: - The features can be printed - 3D have limitations after all. - the materials that can be 3D printed are optically suitable.
