The scattering from multiple multilayered eccentric bianisotropic cylinders is studied at first in the most general case based on the boundary-value approach combined with the generalized separation variables method and the indirect modeling technique according to the equal volume principle. The solution is developed and expressed in terms of a system of simultaneous linear equations of infinite order which is then truncated for numerical computations, and the normally incident wave can be either TEz- or TMz-polarization. Numerical investigation is performed for the co- and cross-polarized echo widths in the far field zone, and the multiple scattering features are demonstrated for various two-dimensional bianisotropic cylindrical composites corresponding to different constitutive models, such as uniaxial and gyrotropic forms, as well as the combination of ordinary ferrite with bianisotropic media.
