Abstract:
Relations are obtained that make it possible to compute the field of the wide-band terahertz pulse in capillary waveguides with a hollow core and a metalized cladding. From the standpoints of maximization of the pulse energy transfer coefficient and time-domain spectroscopy of air, two types of waveguides are investigated: hollow waveguides with a metalized cladding and dielectric-lined waveguides whose hollow core is separated from the metal by a dielectric layer. It is shown that the efficiency of the waveguides of the second type is higher due to their quasi-single-mode operation.

Keywords:
terahertz pulse, terahertz spectroscopy, hollow core waveguide.
