Lorentz invariance of Maxwell's equations in matter
I know that Maxwell's equations of electromagnetism are Lorentz invariant in a vacuum. But what about in a generalized medium, e.g. a metal, a rubber, a dielectric, a magnet? I have read it comes down ...

Refraction vs Special Relativity
Special relativity postulates that the speed of light (while traveling through vaccum) is a constant ($c = 3 \times 10^8 m/s$). But, when light is refracted and change the medium in which it's ...

Special Relativity, refractive index and catching up with a wave
Einstein was partially motivated by the following: With Maxwell's equations, a plane wave is a sinusoidal wave that varies in space in time and moving with speed $c$. These variations are linked by ...
