A method for analyzing the scattering of electromagnetic waves by a ge
neral bianisotropic slab is presented by extending the author's previo
us approaches for anisotropic, chiral, and those periodic media. The a
nalysis is formulated in a unified matrix form, so that scattering cha
racteristics can be obtained by system matrix calculations. The method
can be extended straightforwardly to multilayerd and periodic structu
res. The scattering efficiencies are obtained for the incidence of not
only linearly polarized waves but also circularly polarized waves.
