Investigation on mode coupling and bending loss characteristics of terahertz air-core pipe waveguides

We demonstrate the magnificent flexibility of the terahertz air-core pipe waveguides. By measuring waveguide attenuation spectra, we found that the pipe waveguides can be easily butt coupled with high coupling efficiency and low bending loss.
