Numerical results of the distribution of ${\left|H_y\right|}^2$ in the magneto-plasmonic waveguide. The left and the right parts to the white dashed line are in the absence and the presence of the external magnetic fields inducing g = ±g₀, respectively. The value of g₀, 0.042 is calculated by Eq. (9). The symmetric SPP mode at λ = 800 nm is incident to the left port of the structure. Other parameters are same as in Fig. 2.
