  4. Uniaxial crystals Ordinary ray Principal plane Extraordinary ray Principal plane

  5. Uniaxial crystals ne does not depend on j

  6. E Uniaxial crystals Walk-off angle: Equation of the index ellipse: z k no E ne (q) D q E x H = s b ne x, y or r

  7. qc z k no E ne (q) q b ne x, y or r E L Orienting Uniaxial crystals

  8. Velocities in Uniaxial crystals qc z E E no vp = c/ne (q) q k b ne vr = ray velocity x, y or r L Quote from Born & Wolf: The ray velocity is a useful concept, although, like the phase velocity, it has no directly verifiable physical significance!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
