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 ...

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 ...

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, ...
