Why doesn't infrared radiation pass through objects?
It cannot be due to Raman scattering because $1$ in $10^7$ photons are Raman scattered. It cannot be Rayleigh scattering because Rayleigh scattering of infrared radiation is very low due to the ...

Wave propagation in gyrotropic medium
Given a gyrotropic material with
$$\vec D = \epsilon \vec E + \lambda / c \vec H \\ \vec B = v / c \vec E + \mu \vec H$$
where $\epsilon, \lambda, v, c, \mu$ are constants (no relation ...
