Adjustment of the Z-Bench Transmissometer for Biomedical Measurements at 300 GHz Using a 3-D Printed Back-to-Back Horn

In this paper investigation of a Z-bench transmissometer to accommodate a 3D printed back-to-back horn is presented. Altering the performance of a standard Z-bench by introducing a 3-D printed 300 GHz back-to-back horn system requires a change in the Z-bench configuration. Such changes have been performed and investigated, whilst results of the altered system are demonstrated. The measurement campaign has demonstrated that a Z-bench, with back-to-back horn in operation can lead to an enhancement in the system performance. Additionally, it is demonstrated that 3-D printing can be used to prototype complex devices, such as horns, for sub-THz techniques.
