description: The given work is devoted to the development of collimated THz beam expanders based on high resistivity float zone silicon and polymers. In the course of this research, the existing approaches to simulate expanders have been analyzed, and the approach based on geometric optics has been observed in detail and has been applied. Models have been built in the framework of geometric optics using the Zemax OpticStudio software package, as well as in the framework of wave optics in the COMSOL software package, which has made it possible to reveal significant differences in the pattern of ray propagation with and without wave effects of THz radiation. Modeling has been performed for five different expander lens materials: high resistivity float zone silicon (HRFZ-Si), polymethylpentene (TPX), cycloolefin polymer (ZEONEX), polylactide (PLA), cyclic olefin copolymer (TOPAS). Then, an experimental examination of the already created expander has been carried out in order to determine its performance and the influence of external factors on the quality of its work.As the results of the research, the main parameters of the expander have been determined, including parameters of its lenses, which have caused significant changes to the operation when wave optics have been taken into account, i.e. in real conditions.The results of this work may be used in the future for more effective modeling of collimated THz beam expanders, taking into account the criteria that were determined after all the stages.
