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 [??] [32].
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.
