Since its inception, augmented reality (AR) technology has faced a persistent engineering challenge: achieving a wide field of view (FOV) and excellent display quality within a compact and lightweight ...

The best possible shielding is provided by a solid metal enclosure with no seams, no penetrations, and no apertures. The shielding can’t get any better than that—absolutely no RF leakage. But of ...

Circuits that carry signals via visible and infrared light rather than electric currents are desirable for many applications because they transmit data faster and use less energy. The problem is that ...
