Light that is reflected back from the edge of the medium it is traveling through. When light rays travel at an angle greater than the "critical" angle, which is determined by the medium, the light ...

In an optical fiber, the maximum angle from the axis at which light can remain confined within the core for "total internal reflection." In contrast to the "acceptance angle," which is measured ...

The two research institutes said the multijunction solar cell is based on silicon, gallium indium phosphide (GaInP) and gallium arsenide (GaAs). The device utilizes a specially designed metal/polymer ...
