Physical modeling of electromagnetic scattering in the quasi-optical transmission lines

A new method of physical modeling of scattering characteristics of the objects in near millimeter wave (NMM) and submillimeter wave (SMM) electromagnetic wave regions, i.e., the quasi-optical waveguide modeling method (QMW) has been suggested and realized. The principle of designing the quasi-optical waveguide micro-compact ranges (MCR) has been proposed. It is a new class of radio metering systems for scientific and technical application. MCR based on the hollow dielectric waveguide type of "hollow dielectric beamguide" - type and broad-band quasi-optical devices and components in NMM and SMM-wave ranges have been offered and realized for experimental study of energy, amplitude-phase and polarization scattering characteristics of physical objects or their scale models by QWM method. The results of the present study and the above recommendations have found practical application in experimental investigation of scattering characteristics of different objects by QWM method in NMM and SMM-wave ranges using micro-compact ranges. In some cases they are alternatives for big, complex, and very expensive systems currently used for these purposes.
