Abstract

With introduction of Bloch impedance we proposed a modified boundary conditions for materials where spatial dispersion appears. The bi-anisotropic medium is consider as an asymmetric one with dependence of wave impedance for forward and backward propagation directions. The similar dependence is observed for ratio of polarization and magnetization as well for Bloch impedance. It is shown the essential of application of Bloch impedance in the retrieving of constitutive parameters from scattering parameters.
