Rectangular waveguide is the most common type of transmission line used in microwave communication. It is a metallic transmission line ideally suitable for microwave frequencies and is employed to ...

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 ...

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 ...

Researchers fabricated 20mm length waveguides made of the superconducting metal niobium (right). It shows improved conductivity compared with normal metal materials such as a gold-plated tellurium ...

Scientists announce the discovery of slab waveguides based on the two-dimensional material hexagonal boron nitride. The U.S. Naval Research Laboratory (NRL), in collaboration with Kansas State ...

(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 ...

A team of researchers at the University of California, Los Angeles (UCLA) has introduced a novel framework for designing and creating universal diffractive waveguides that can control the flow of ...

Waveguides generate digital images directly in the field of vision and enable smart glasses such as the Meta Ray-Ban. We explain the technology behind them. Waveguides, as they are known in German, ...
