Analysis of Symmetric Electromagnetic Components Using Magnetic Group Theory

We discuss a method of analysis symmetric electromagnetic components with magnetic media based on group theory. In this description, some the irreducible corepresentations assume complex values exp(iθ) real parameter θ. A possible physical interpretation is given. demonstrate application symmetry-adapted linear combination combined corepresentation theory to problem current modes in an array magnetized graphene elements where Faraday and Kerr effects can exist. The are described by symmetry C4 or C4v(C4). scattering matrix its eigensolutions defined analyzed numerical simulations presented as well. An example waveguide C4v(C2v) specific type degeneracy also discussed.
