For most design engineers, study of waveguide technology ended when they got their last degree. The only time waveguide comes up is to use it as a last resort in applications such as millimeter-wave ...

Comprised of judiciously engineered microscopic photonic structures with subwavelength features, the concept of metasurface and metamaterials have proven fruitful results in the realm of meta-optics.

Traditional wired systems have their own limitations in industrial settings. For example, conductor bars are restricted to analog signals, festoons and cable reels are limited to 330 feet for Ethernet ...
