Double negative materials with negative refractive index whose mass density and bulk modulus are simultaneously negative were demonstrated using a one-dimensional waveguide with membranes and side ...

WE have extended the scope of a method recently described 1 for the measurement of refractive indices of liquids in thin films, and have obtained evidence of the double refraction of the ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

It turns out that the phenomenon of birefringence is very practical. For example, the Vikings used double refraction of some crystals for navigation. Present-day liquid crystal monitors use the ...

LASER COMPONENTS now also offers Nd:YLF, which is a double refractive crystal that emits polarized light at perpendicular angles at 1047 and 1053 nm. In addition, there are also transitions at 1.3 µm.

The change in direction of a beam of light as it travels from one material to another is called refraction. The normal is a construction line drawn at right angles to the surface of the glass block.
