In the present paper, a hollow dielectric waveguide (HDW) is theoretically considered as a field former to be employed in the laboratory investigations of the scattering characteristics of physical objects or their scaled models by the method of quasioptical-waveguide modeling (QWM) in the near-millimetric /submillimetric wave range. The field quality criteria developed for the HDW-enclosed operation volume yield the easy and sufficiently accurate for practical purposes analytical relations which allow the designer to select optimum HDW parameters controlling the desired field characteristics within the operation volume. Applying the minimization criterion to longitudinal variations of the field in the operation volume reveals that a quasioptical forming structure of the HDW type admits a far greater extent of the operation volume as compared with free space. This opens the way to measure very extended scatterers through their scaled models which may be as long as hundreds and even thousands of the wavelengths.
