Meta surfaces can be designed to steer sound or electromagnetic waves in arbitrary directions, or act as beam splitters, according a team from Aalto University in Finland and Duke University North ...

Light collection efficiency is an important factor that affects the performance of many optical and optoelectronic devices. In these devices, the high reflectivity of interfaces can hinder efficient ...

1. The reflection of light from the surfaces of many kinds of leaves has been measured by means of a direct reading spectrophotometer, the measurements being made normal (that is, at an angle of 90⚬ ...

Driven by the demand for smaller and smaller consumer products and semiconductor devices, manufacturers need thin planar optics for a host of applications. This means material and optics manufacturers ...
