A property of a material that changes the speed of light, computed as the ratio of the speed of light in a vacuum to the speed of light through the material. When light travels at an angle between two ...

Among the various sensing modalities available for bioprocess operations, index of refraction (IoR) is intriguing for its simplicity and capability for sample-less, real-time readout. A group led by ...

What makes it distinct from other metamaterials is that it is made entirely from semiconductor material — the stuff found in computer chips and prized for its ability to act as ...
