Under some circumstances, one may wish to specify the target orientation
such that
(the direction of propagation of the radiation)
and
(usually the first polarization direction)
and
(=
refer to certain directions
in the TF. Given the definitions of the LF and TF above, this is simply an
exercise in coordinate transformation.
For example, one might wish to have
the incident radiation propagating along the (1,1,1) direction in the TF
(example 14 below). Here we provide some selected examples:
