class representing the optical refractive index tensor

The rank 2 refractive index tensor describes how light of a given propagation direction is slowed down by the crystal. Its anisotropy is what makes a crystal birefringent, and is the basis of the simulated thin section colours computed by spectralTransmission.

Syntax

rI = refractiveIndexTensor(M,cs)

Input

M 3x3 matrix
cs crystal symmetry

Output

rI refractiveIndexTensor

Class Properties

M the tensor coefficients
rank always 2
CS symmetry the coefficients refer to

Example

rI = refractiveIndexTensor.calcite
rI = refractiveIndexTensor (Calcite)
  rank: 2 (3 x 3)
 
  1.66     0     0
     0  1.66     0
     0     0 1.486
