Is there a wave equation describing electromagnetic waves in materials?
Solutions to the usual wave equation for electromagnetic waves have the property that wave components of different wavelengths travel at the same phase speed $c$, so no dispersion occurs.

Ampere's Circuital law in non-linear and dispersive medium
For a linear and non-dispersive medium $\vec{B} = \mu \vec{H}$.
So amperes circuital law in integral form (without Maxwell's correction term) can be written in two ways
$\oint_C \vec{B}\cdot\vec{dl} =...

Refractive index and electric susceptibility
Suppose we have a complex refractive index $n_{ref}=n+ik$ whose value is given at a precise frequency $\omega_l$ from experimental data. We know that the imaginary part is responsible for the loss/...
