(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 ...

Waveguide transitions serve as critical interfaces between planar transmission lines and three-dimensional waveguide structures, enabling efficient energy transfer in millimetre-wave systems. These ...

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 ...

An ideal waveguide display for augmented reality would feature a single-layer waveguide substrate combined with dispersion-free couplers. While metasurfaces have been explored as a potential solution ...
