Reflection from uniaxial crystals: symmetries, and formulae for near-normal incidence
{{output}}
The following symmetries and interrelationships are established: the direct reflection amplitudes r ss,r pp are independent of the signs of the direction cosines of the optic axis. For example, they are unchanged by ϕ→π-ϕ or ϕ→-ϕ, where ϕ is the azimut... ...
