All of them!!

3. How do ‘one way’ mirrors work?
The cheap version (and most often used), makes use of a BRIGHT ‘interrogation’ room and a darkened ‘observation’ room. Between the two is a partially reflecting mirror (~50%). Bright room occupants see their own reflection from mirror. Dark room occupants see light from light room through partially reflecting mirror
More expensive method: Mirror fabricated as ‘optical diode’ or ‘optical isolator’.

4. Anisotropic Media

5. Ellipsoid representing symmetric tensor

6. Normal Modes with CUBIC principle Axes
Normal Modes: when a particular polarization, after passing through an optical material, is unchanged.
Eg. x direction linear polarization in gives x direction linear polarization out
Eg. RHC polarization in gives RHC polarization out.
