(a) Electric field (E-field) distribution of a conventional line wave propagating along a bent path at f = 8 THz, showing significant scattering and instability. (b) E-field distribution of the quasi-line wave along the same bent path and frequency, demonstrating improved stability and reduced scattering, highlighting the quasi-line wave’s superior performance in maintaining wave confinement and propagation through curved geometries.
