Figure 4. Effects of different parameters on derived EMT predictions_.

The frequencies at which ε_eff, μ_eff,x, or μ_eff,y become zero according to Eq. (1), as functions of various parameters are pictured as curves. For comparison, the frequencies of the lowest monopolar and dipolar states at the Γ point, which are obtained from the band structure calculations using COMSOL, are also plotted in dots. (a) Effects of changing a_s/b_s with fixed ε_s = 12, μ_s = 1, and f = 0.126. (b) Effects of changing ε_s, with fixed a_s/b_s = 1.3, μ_s = 1, and f = 0.126. (c) Effects of changing f, with fixed a_s/b_s = 1.3, ε_s = 12, and μ_s = 1. (d)−(f) Similar conditions as those shown in (a) – (c), but the dielectric cylinders (μ_s = 1) are replaced with magneto cylinders (ε_s = 1).
