The refractive index of a material defines the angle through which light is bent when it travels between a material and the vacuum. Ordinary materials such as glass have refractive indices between one ...
Physicists at Harvard University in the US have built a silicon waveguide that exhibits a refractive index of, or close to, zero when operating at near-infrared telecom wavelengths. The waveguide can ...
EurekAlert!: High-refractive-index material retains high transmissivity after annealing at 850 degrees C
EDN: New on-chip material has a refractive index of zero, meaning light can travel infinitely fast through it
Researchers at Harvard’s John A. Paulson School of Engineering and Applied Sciences have announced the first on-chip metamaterial with a refractive index of zero — meaning the phase of light can ...

A comprehensive reference database of dimensioned drawings documenting the standard measurements and sizes of the everyday objects and spaces that make up our world.
Humans, the most dominant form of animal life on the planet, are beings whose properties, dimensions, and traits have the most direct impact on the built environment. Connected to the measurements and sizes of the body, designed objects in everyday spaces are created to best support use by humans.
A US brick is a type of brick that is made in the United States. It is typically made from a type of clay called fireclay, which is fired in a kiln at temperatures of around 1100 degrees Celsius. US bricks are known for their durability, strength, and variety of colors. Standard USA Bricks are recognized by their nominal size of 4” x 2.25” x 8”. The actual dimensions of Standard USA ...
