                         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.",
