Analysis and Optimization of a Quasioptical Waveguide-based Microcompact Testing Range for Submillimeter Waves
要約
A technique is suggested for estimating and optimizing the basic parameters of the microcompact test range built around a quasi-optical transmission line, like hollow dielectric beam guide (HDBG). The microcompact range (MCR) is intended for laboratory studies of scattering properties of physical objects through quasi-optical modeling in a submillimeter-wavelength guide. Analytical expressions have been obtained relating the MCR geometry and electromagnetic parameters with characteristics of the HDBG. These equations are analyzed with account of the real-life excitation characteristics of the HDBG. It has been shown that because of the imperfect excitation of the principal mode at the HDBG input, the MCR length should be increased essentially to keep dimensions of the work area unchanged at a specified admissible level of variations in the incident field. Conditions have been formulated for ensuring the required purity of the incident field in the work area of the MCR for fixed magnitudes of the excitation efficiency and self-filtering of the principal mode in the HDBG.
