The generation of polarization radiation by electron beams passing near dielectric objects has attracted considerable attention due to its potential applications, such as beam parameter diagnostics and the generation of intense electromagnetic radiation in the THz and sub-THz frequency ranges. Among the various forms of this radiation, Cherenkov diffraction radiation (ChDR) is particularly noteworthy. ChDR arises when high-energy electrons travel parallel to and in close proximity to a long dielectric interface. The characteristics of this radiation are influenced by the properties of the charged particles, the target material, and its configuration. To produce radiators with the required precision, advanced technologies for fabricating dielectric samples with complex geometries are essential. One promising approach is 3D printing using fused filament fabrication (FFF) of plastics. However, before implementing this method, a thorough investigation into the dielectric properties of these plastics must be conducted to ensure their suitability.
