Abstract

We study and compare terahertz wave propagation in trapezoidal hollow-core aluminum waveguides with and without ridge with respect to attenuation and single-mode spectral bandwidth. Furthermore, we demonstrate a waveguide-based terahertz interferometer for terahertz sensing based on pure amplitude measurements without the necessity for a direct phase measurement.
