abstract = "Forward and backward reflection and transmission scattering (S-)
parameters of a metamaterial (MM) structure of bi-anisotropic
slabs in cascade are analyzed. Signal flow graph technique is
applied in this analysis for a cascaded connection of two and
three bi-anisotropic MM slabs with different orientations. We also
investigated effects of geometrical parameters (fabrication
tolerances) of individual MM cells on forward and backward
reflection and transmission S-parameters of cascade connection of
MM cells. We note from our analysis the following important
points. First, forward and backward reflection S-parameters become
equal to one another for a MM structure composed of an even number
of bi-anisotropic MM slabs (individually characterized by
non-identical forward and backward reflection S-parameters) with
proper orientations only if there exists symmetry of the structure
in the propagation direction. Second, it is noted that it is not
possible to obtain identical forward and backward reflection
S-parameters of a MM structure composed of an odd number of
bi-anisotropic MM slabs. Finally, reflection asymmetry
(bi-anisotropy) of cascade connection of MM cells generally is
enhanced for a change in geometrical parameters of individual MM
cells.",
