Ferroelectric PVDF cladding terahertz waveguide

A new type of flexible terahertz-wave hollow waveguide has been developed using ferroelectric polymer poly vinylidene fluoride (PVDF) as the cladding material. The transmission efficiency of the PVDF waveguide was better than a metal hollow waveguide with the same size and structure as the PVDF waveguide. This paper also reports the bent-angle dependencies of the transmission efficiency of the hollow PVDF.
