Researchers demonstrate a new technique for suppressing back reflections of light—better signal quality for sensing and information technology. Microresonators are small glass structures in which ...

When we look in a mirror, we are used to seeing our faces looking back at us. The reflected images are produced by electromagnetic light waves bouncing off of the mirrored surface, creating the common ...

Before diving into ray tracing ("RT" for short), let's first take a look at how illumination works in the real world. From the micro-perspective, the surface of an object illuminated by a ray of light ...
