We can also use wavelengths to calculate refractive index. By substituting \(v_{1}=f\lambda _{1}\) and \(v_{2}=f\lambda _{2}\) into \(n=\frac{v_{1}}{v_{2}}\) then ...

To measure the index of refraction ... of the transmittance. The second configuration (prism sample) was formed by etching the film at an angle β to the film surface, using FIB.

The researchers also succeeded in effectively controlling the light in the visible region using the newly ... so far have high transmittance with low refractive index, or, conversely, high ...
