Transformation optics represents a new paradigm for designing light-manipulating devices, such as cloaks and field concentrators, through the engineering of electromagnetic space using materials with ...

DigiLens, creators of waveguide optics, today announced a “deeper” partnership with Mitsubishi Chemical to bring a plastic version of its waveguide technology to the market. The companies claim the ...

DigiLens, a maker of waveguide optics for AR glasses, today announced a second close of its Series D funding round, claiming a $530 million valuation. DigiLens is one of several companies building ...

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 ...

Engineers have developed the thinnest optical device in the world -- a waveguide that is three layers of atoms thin. The work is a proof of concept for scaling down optical devices to sizes that are ...

Waveguide has many practical uses in high-powered RF systems, as covered in the last tutorial. Specifically, it is used as a transmission line for higher frequencies ranging from the UHF band up ...

Anyone who has done an electronic engineering qualification will at some point have had to get to grips with transmission lines, and then if they are really lucky, waveguides. Perhaps there should be ...

Twisted sisters: light with OAM values of +1 (top) and 0 (bottom) before (left) and after (centre) passing through the doughnut wave guide. The column on the right shows the inference of the two ...
