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 ...

Holographic images: the two figures on the left are two holographic images produced by a leaky-wave metasurface at two different distances from the device surface. The other figures are distinct ...

Holographic photopolymers can be cast onto and around other optical elements, then patterned with a 3D routed waveguide to form hybrid integrated photonics. While multi-photon initiation can be used ...
