High-powered satellites use electromagnetic waveguides to deliver energy from one component to another. Typically, they are ...

Last month, this column discussed some of the fundamental concepts of selecting coaxial transmission lines. That included low-power flexible lines as well as some issues involving high-power rigid ...

(Nanowerk Spotlight) The concepts of metamaterials and metasurfaces have spawned massive novel applications in free-space optics. However, recent research also indicates that they possess prominent ...

Modern satellites rely on electromagnetic waveguides—hollow structures that carry high-power signals between components such ...

Rising from inside the transmission equipment room and reaching all the way to the antenna at the top of the tower is a vital link in the broadcast chain — the RF feeder or transmission line. There ...

International optics and photonics technology group Schott, which also manufactures materials and components for Augmented Reality (AR) waveguides, has joined forces with Israeli company Lumus, a ...

The debuts follow a milestone year in 2025 where Lumus provided the waveguide for the Meta Ray-Ban Display AR glasses, demonstrating the optical performance and mass-manufacturability of geometric ...
