TLDR
A novel twist on the classical tube waveguide where a thick and highly lossy cladding layer is introduced to attenuate the field in the cladding and thus prevent interference with the core field, and thus represents a significant advance of the field of THz dielectric waveguides suitable for the 0.3–1 THz band.Abstract:
