The key idea of this work is application of the concept of magnetic groups and Curie's principle to the tensor description of complex and bianisotropic media. It is shown how to find the symmetry group of the media under external perturbation and to calculate the structure of the constitutive tensors starting from the symmetry of the medium. The theory may be used as a first step in the problem of new artificial material synthesis.
