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 ...

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 ...

RF waveguide combiners and dividers are circuits that combine or divide radio frequency (RF) signals. RF waveguide combiners accept several input signals and produce a single, combined output signal.

The first theoretical models of the propagation of an electromagnetic field in a waveguide date back to the second half of the 19th century (Hertz, Debye, Rayleigh). The technological fallout for long ...

Researchers have designed and demonstrated stretchable waveguides that maintain efficient, stable signal transmission of surface plasmon polaritons even when bent, twisted or stretched. These ...

In this article we provide an introduction to near-eye optics, analyze the evolution of waveguides, then narrow the field down to holographic waveguides. Throughout we will examine the players in the ...

Waveguide-to-coaxial adapters are RF adapters used to connect waveguide devices to coaxial components. What are Coaxial Cables and Waveguides? Coaxial cables are electrical cables with three or more ...

High-speed optical circuits and sensors generally require strict control over light polarization to minimize loss and cross-talk in photonic devices such as waveguides. An A*STAR team now predicts ...

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, ...
