Transverse spin (\({\overrightarrow{S}}_{surf}\)) and the spin-orbit locking in an ENG/MNG waveguide. For the spin-up \(({\overrightarrow{S}}_{surf} > 0)\), the wave-vector or momentum in the MNG (ENG) metamaterial is positive (negative). However, for the spin-down \(({\overrightarrow{S}}_{surf} < 0)\), the momentum in the MNG (ENG) metamaterial is negative (positive). The 2D magnetic-field distributions in the z direction at frequency of 2.7 GHz for rotating source with different handedness located in ENG or MNG metamaterial are shown in the four insets.
