Abstract :
In this work, we investigate the propagation behavior of THz surface-wave pulses along bare and dielectrically coated metal wires. Frequency-dependent attenuation and dispersion parameters are determined in the range of 0.02 THz to 0.4 THz with an optoelectronic time-domain measurement setup. Our results are in good agreement with numerical field simulations considering the propagation of an axial Sommerfeld surface-wave with metallic and dielectric losses. We discuss the influence of wire radius on wave propagation behavior and the application of THz Sommerfeld wires for sensing
