Figure 2. Isofrequency curves in wavevector space for light propagating in the layered structure under various values of external magnetic B at 1 THz.

Figure 2

Blue (green, red) line shows an hyperbolic type of dispersion relation that corresponds to B = 0 Tesla (2.5 Tesla, 4.14 Tesla). The real parts of (εx, εy) for blue, green and red lines are (5.088, −70.34), (5.51, −12.21) and (0.0545, −0.2734), respectively.
