Numerical Result (image) Forschungsverbund Berlin Share Print E-Mail Caption Figure 2 shows the numerical results for the distribution of the plasmon intensity demonstrating channel switching.The reversal of the direction of the external magnetic field leads to a switching of the SPP propagation from channel 1 in (a) to channel 2 in (b). The metal waveguide is made from gold and the surrounding ferromagnetic dielectric from Bi-substituted iron garnet (BIG).
