Characteristics of guiding TE plasmon-polaritons (a) and distance of TE plasmon mode from light line (b). Core radius R = 1 μm. Permittivities of the core and the outer mediums are equals. Filled region in (b) correspond to the values Inline graphic, what may be observed in some materials at near the resonance conditions or in ε-near-zero materials and metamaterials, logarithmic scale is used for both axes.
