Abstract :
The shift operator (SO) method is extended to the case of electric anisotropic dispersive medium by taking magnetized plasma for example. The SO-FDTD formulations are derived based on the permittivity tensor in magnetized plasma and Maxwell curl equations of anisotropic media, in which the transfer matrix between the principal and the laboratory system is used. The LCP and RCP eigenwave reflection and transmission coefficients of magnetized plasma layer, the backward RCS of a plasma sphere in an external dc magnetic field of different directions are computed by proposed method and analyzed. The computed results indicate the correctness and feasibility of our method.
