inhomogeneities with the wave launch belonging to the k ⊥ B
o
mode, has
not been reported earlier in such geometries. In the subsequent sections,
we attempt to obtain numerical solutions in such a conguration based on
the experimental observations and investigate the physics of the interaction.
Modeling
In general, there is no perfect TE and TM mode in plasma-lled waveguides
[20,21]. However, from the experimental results, the following points may
be noted: (i) The dipole structure in Figure 13.5b indicates that the electric
eld has a
θ
dependence. For a TM mode, E
θ
= 0. (ii) A nite B
z
is obtained, as
shown in Figu ...
