It is assumed that the anisotropy axis is orientated in the incidence plane
under an arbitrary angle [beta] with the normal to the interface (Figure 1).
The incidence electric field is expressed in (1), and the temporal behavior of the incidence plane
wave is given by a third-order derivative of the modulated-Gaussian pulse (see Fig.
The incidence angle is denoted with [theta], [phi] is the azimuthal angle, and [psi] is the angle between the incidence plane
and [??] .
It should be noted that since we are only considering propagation in symmetry planes both paths are located in the incidence plane
. For the transversely isotropic case of propagation in the plane 1-2, propagation of the wave front and energy flux coincide and the distinction has to be made only in the anisotropic plane 1-3.
We assume that the incidence plane
wave impinges with the angle [[theta].sub.i], as shown in Figure 2.
where [k.sub.x,0] = -[k.sub.0] sin [[theta].sub.in] cos [[phi].sub.in], [k.sub.z,0] = [k.sub.0] cos [[theta].sub.in], [a.sup.e.sub.1] = cos [alpha] sin [[theta].sub.in], [a.sup.h.sub.1] = sin [alpha] sin [[theta].sub.in], and [alpha] is an inclination angle of the incoming field on the incidence plane
