Refractive index in metamaterials [duplicate]
Why do metamaterials have $n<0$?
They are defined to be those materials with $\varepsilon <0$ and $\mu<0$, but the definition of the refractive index is
$$n=\sqrt{\frac{\varepsilon\mu}{\...

Why does optical media have different refractive indices?
Optical density is a measure of the refracting power of a medium. In other words, the higher the optical density, the more the light will be refracted or slowed down as it moves through the medium. ...

Temperature-induced wavelength shift of optical coatings?
Optical coatings designed for reflection or anti-reflection are made of many thin layers which will expand when heated. What will the effect be on the wavelengths the coating will reflect when the ...
