When the magnetic field is strong enough, the effective galvano-magnetic thermoelectric properties of periodical metamaterial exhibit very strong variations with the direction of the applied magnetic field with respect to the symmetry axes of the metamaterial nanostructure. This is qualitatively similar to other effects recently predicted by us: magneto-induced angular magnetoresistance anisotropy (which was verified experimentally) and magneto-induced magneto-optical anisotropy. The angular magneto-induced anisotropy of the thermoelectric moduli depends upon the inclusion radii R. For sufficiently large values of dimensionless magnetic field, additional maxima or minima in (n01)-like directions appear with decreasing inclusion radii. The current results can be useful for studying the possibility of increasing the thermoelectric figure of merit by application of a strong magnetic field.
