Abstract: We present the design of rectangular waveguide excited metasurfaces for near-field shaping using a coupled dipole framework. Waveguide-fed metasurfaces are array-like radiating systems ...

This article evaluates some of the strengths and weaknesses of reflective and diffractive waveguides used in augmented reality (AR) optics for smart glasses. Waveguides are the optics used in smart ...

The only thing more impressive than Gail being an exceptional handmade jewelry and resin artist is the fact that she is not a fan of gatekeeping her expertise. This video serves as a prime example of ...

"We show that this design can, in principle, find half of all existing Earth-like planets orbiting sun-like stars within 30 light-years in less than three years." When you purchase through links on ...

Researchers have now developed a new superior hardware platform for artificial intelligence accelerators using photonic integrated circuits on silicon chip. Co-packaged optics (CPO) technology can ...

Augmented reality (AR), the technology that overlays digital content onto what users see around them in real-time, is now widely used in the retail, gaming and entertainment industries, as well as in ...

Augmented-reality (AR) technology is rapidly finding its way into everyday life, from education and healthcare to gaming and entertainment. However, the core AR device remains bulky and heavy, making ...

Meta’s Orion AR glasses prototype is expensive to make—like $10,000 per pair, expensive. Orion’s most pricey component is undoubtedly its custom silicon carbide waveguide lenses, although Meta says it ...
