All the signals that propagate through a waveguide are above a certain frequency, called the cut-off frequency. Below the cut-off frequency, waveguides fail to transfer wave energy or propagate waves.

Nettet14. nov. 2024 · A hollow-core PCF was fabricated using the 3D-printing method . The fabricated waveguide showed a lower loss of about 0.02 cm −1 in the THz band.
