(a) Measured and theoretical group velocities, , of the THz pulse on the PS wire with various core diameters. At short wavelengths, approaches 0.63C for a PS wire. (b) Measured and theoretical group velocities of THz pulse on thick PS and PE wires. (c) Measured and theoretical waveguide dispersions, , of THz pulse on PS wire with various core diameters. (d) Measured and theoretical waveguide dispersions of THz pulse on thick PS and PE wires.

FIG. 3.

(a) Theoretical normalized waveguide dispersions of thick PS wire with various cladding indices. (b) Measured (solid and dashed lines) and simulated (solid and open circles) waveguide dispersions of PS wire with PE and tryptophan powders in wire cladding regions.
