We present an omnidirectional mirror for the terahertz range made from polypropylene and high-resistivity silicon. The structure is characterized by time-domain terahertz spectroscopy. The experimental data are in good agreement with transfer matrix calculations. In the frequency band between 319 and 375GHz the mirror is highly reflecting for all incidence angles and s as well as p polarization.

We note that this somewhat reduces the overall reflectivity of the mirror.

Note that the experimental reflectivity in Fig. 5 for 60° and s polarization in the reflection band signal is already somewhat smaller than the (real) theoretical value.
